Move search to an entire class of its own.

The initial motivation for this was to make the "more_after_limit"
feature, which would help the UI to not show a next page button when
the number of results was exactly equal to the limit.

However, in order to surface this more_after_limit status using only
the old search generator, it would have to be a special yield at the
end. I was getting tired of the special yields like give_back_params
at the beginning and warning_bag at the end, and this would be worse.

There is a lot of sideband information about the search that is now
more easily accessible when the search is its own object.

'''
FILE METADATA
=============
area, aspectratio, width, height, bytes, duration, bitrate:
A dotdot_range string representing min and max. Or just a number
for lower bound.
extension:
A string or list of strings of acceptable file extensions.
extension_not:
A string or list of strings of unacceptable file extensions.
Including '*' will forbid all extensions, thus returning only
extensionless files.
filename:
A string or list of strings in the form of an expression.
Match is CASE-INSENSITIVE.
Examples:
'.pdf AND (programming OR "survival guide")'
'.pdf programming python' (implicitly AND each term)
sha256:
A string or list of strings of exact SHA256 hashes to match.
within_directory:
A string or list of strings or pathclass Paths of directories.
Photos MUST have a `filepath` that is a child of one of these
directories.
OBJECT METADATA
===============
author:
A list of User objects or usernames, or a string of comma-separated
usernames.
created:
A dotdot_range string respresenting min and max. Or just a number
for lower bound.
has_albums:
If True, require that the Photo belongs to >=1 album.
If False, require that the Photo belongs to no albums.
If None, either is okay.
has_tags:
If True, require that the Photo has >=1 tag.
If False, require that the Photo has no tags.
If None, any amount is okay.
has_thumbnail:
Require a thumbnail?
If None, anything is okay.
is_searchhidden:
If True, find *only* searchhidden photos.
If False, find *only* nonhidden photos.
If None, either is okay.
mimetype:
A string or list of strings of acceptable mimetypes.
'image', 'video', ...
Note we are only interested in the simple "video", "audio" etc.
For exact mimetypes you might as well use an extension search.
TAGS
====
tag_musts:
A list of tag names or Tag objects.
Photos MUST have ALL tags in this list.
tag_mays:
A list of tag names or Tag objects.
Photos MUST have AT LEAST ONE tag in this list.
tag_forbids:
A list of tag names or Tag objects.
Photos MUST NOT have ANY tag in the list.
tag_expression:
A string or list of strings in the form of an expression.
Can NOT be used with the must, may, forbid style search.
Examples:
'family AND (animals OR vacation)'
'family vacation outdoors' (implicitly AND each term)
QUERY OPTIONS
=============
limit:
The maximum number of *successful* results to yield.
offset:
How many *successful* results to skip before we start yielding.
orderby:
A list of strings like ['aspectratio DESC', 'created ASC'] to sort
and subsort the results.
Descending is assumed if not provided.
yield_albums:
If True, albums which contain photos matching the search
will be yielded.
yield_photos:
If True, photos matching the search will be yielded.

PHOTO PROPERTIES
area, aspectratio, width, height, bytes, duration, bitrate:
A dotdot_range string representing min and max. Or just a number

usernames.
created:
A dotdot_range string respresenting min and max. Or just a number
for lower bound.
extension:
A string or list of strings of acceptable file extensions.
extension_not:
A string or list of strings of unacceptable file extensions.
Including '*' will forbid all extensions
filename:
A string or list of strings in the form of an expression.
Match is CASE-INSENSITIVE.
Examples:

has_albums:
If True, require that the Photo belongs to >=1 album.
If False, require that the Photo belongs to no albums.
If None, either is okay.
has_tags:
If True, require that the Photo has >=1 tag.
If False, require that the Photo has no tags.
If None, any amount is okay.
has_thumbnail:
Require a thumbnail?
If None, anything is okay.
is_searchhidden:
Find photos that are marked as searchhidden?
If True, find *only* searchhidden photos.
If False, find *only* nonhidden photos.
If None, either is okay.
Default False.
mimetype:
A string or list of strings of acceptable mimetypes.
'image', 'video', ...

QUERY OPTIONS
limit:
The maximum number of *successful* results to yield.
offset:
How many *successful* results to skip before we start yielding.
orderby:
A list of strings like ['aspectratio DESC', 'created ASC'] to sort
and subsort the results.
Descending is assumed if not provided.
warning_bag:
If provided, invalid search queries will add a warning to the bag
and try their best to continue. The generator will yield the bag
back to you as the final object.
Without the bag, exceptions may be raised.
YIELD OPTIONS
give_back_parameters:
If True, the generator's first yield will be a dictionary of all the
cleaned up, normalized parameters. The user may have given us loads
of trash, so we should show them the formatting we want.
yield_albums:
If True, albums which contain photos matching the search
will be yielded.
yield_photos:
If True, photos matching the search will be yielded.
