This hook had a bug where you couldn't select text because every
time you push a button, including ctrl+a or shift+left/right, the
cursor position gets reset and then deselects immediately.
So let's only reset the content and cursor only when text changes,
so arrow keys and ctrl don't have any negative effects.
This was a dumb bug. Because the version was included in the pragmas
that get set on every load, the database was receiving the new
user_version simply by setting skip_version_check=False and letting
the regular pragmas load, so all future checks passed without
having to run the db upgrader.
Unfortunately, when adjusting the box's value, it causes the datalist
to disappear, and it only comes back after you press another key.
I can't figure out how to make the datalist reappear automatically
with js.
Now that all <a> tags are pointy, there is no need for this fake link.
Its only purpose was to make <a>s that had an onclick but no
url get the ol' pointy.
I'm not entirely happy with the way that native drag-and-drop looks,
the transparent bit that you hold while dragging looks dumb.
Will have to look into control / shift clicking to multiselect.
Also just using browser confirm() for now since I haven't made my
own dialog for that kind of thing yet.
At the moment, tag_objects have an option for a javascript void
link for the purpose of getting a pointer cursor without a real link.
Well I want to phase those javascript void links out so let's just
make a tags always pointy.
