Always store the original string form and convert it to the desired type
on demand. In most cases this is significantly faster as typically only
a few of the parameters in a line are actually read. In addition, this
makes it so that parameters which did not actually change are always
reserialized in their original form.
Delete VariableData as it's no longer used by anything.
Closes#1513.
This eliminates the need to explicitly delete the parsed blocks.
Also go ahead and remove AssDialogue::Blocks since it's really not a
very good idea in general.
It is very unlikely that anyone has ever actually used ASS2 for
anything, and in practice it was not usable anyway as the bottom margin
was always either ignored or blindly overwritten.
I'm not sure if this fixes any current actual problems as using slightly
stale data is normally only a problem when lines are being deleted, but
it's easier to fix it across the board than to figure out where it is
and isn't needed, and the speed impact of batching is trivial.

Convert all coordinates within the visual tools to Vector2D, which has
been significantly extended. Eliminates a lot of issues with accumulated
rounding errors and simplifies a lot of code.
Modernize the visual tools' interactions with the rest of Aegisub by
connecting to signals directly rather than routing everything through
the video display and converting the main visual tool mode toolbar to
the command system.
Extract all references to OpenGL from the visual tools and move them to
OpenGLWrapper as a first step towards making it possible to implement an
alternative video renderer. In the process, eliminate all uses of OpenGL
immediate mode.
Fix a bunch of minor issues and general instability.

Switch to a bitmask with much more finely-grained information about what
changed in the commit, fixing a few potential correctness problems and
significantly improving the performance of several scenarios where commits
are spammed very frequently.
Originally committed to SVN as r5590.
Rather than everything having to separately commit changes to the ass
and then tell the subs grid to notify various parts of Aegisub about the
changes, committing the AssFile now triggers an event which objects
listen for.
AssFile::Commit now also has an argument to indicate what sorts of
changes were made to the file. For now these types are very broad.

Don't display error messages and try other providers when the user
cancels loading a file.
Remove files from the MRU lists if they can't be found.
Closes#717.
Originally committed to SVN as r4717.
This happens to fix most of the undo issues, as it's now much harder to
have uncommitted changes to the file.
Closes#355 and #586.
Originally committed to SVN as r4699.
Make the undo and redo stacks non-static members of AssFile, making it
theoretically possible to have multiple open AssFiles with working undo.
Slightly improve tracking of whether the file is modified: saving,
making a change, then undoing the change now results in the file being
shown as unmodified as with most programs with undo.
Add basic undo coalescing support.
Originally committed to SVN as r4667.
