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.

The old toolbar code didn't actually support any nontrivial
customization of toolbars, as it had a hardcoded list of commands which
would be enabled or disabled, and the checks for enabling/disabling
toolbar buttons was done only in the specific situations which those
commands used.
Make icon size a user customizable option and add support for
dynamically changing it at runtime.

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.
Originally committed to SVN as r4901.
Makes the click event handler for the grid no longer slow when video
autoscroll is enabled, making it harder to accidently select multiple
lines.
Makes seeking speed no longer limited by decoding/rendering speed;
seeking faster than video can be decoded simply results in dropped
frames.
Makes editing the file while a slow-rendering frame is visible far more
responsive.

Kill vfr.h and vfr.cpp and use the libaegisub versions of them instead.
Rather than the globals VFR_Input and VFR_Output, everything related to
frame rate is now part of the video context. Most things which used to
use VFR_Output now call VideoContext::TimeAtFrame etc.; video providers,
rather than modifying VFR_Input directly, now have getters for their
frame rates which VideoContext calls. Read-only public access to
VFR_Input and VFR_Output are still provided (hopefully temporarily) for
a few things which were awkward to do through VideoContext.
The Avisynth provider now might correctly handle VFR MKVs which can be
opened with DirectShowSource but not DSS2.
Rework keyframe handling as well, so that it continues to match the vfr
handling in design and implementation.
Originally committed to SVN as r4662.
Rather than just have a single Refresh method that gets called whenever
something happens that could possibly be of interest to the visual
tools, add seperate methods for signaling frame number changes and
changes to the file, and use the new SelectionController stuff for other
things that used to merit a Refresh. This eliminates a large amount of
redundant reparsing of lines which happened on paint, as well as a large
number of redundant repaints.
Frame data is now only uploaded to the video card when the frame number changes
rather than when anything at all changes, slightly improving performance when
using mesa's software opengl implementation.
Vector clip and drag tools now do a slightly better job of not
discarding the user's selection for no apparent reason, and strange
selection behavior from clicking on visual features should now be
entirely fixed.
Everything but the constructor and toolbar event handler in the visual
tool implementations are now private.
