Despite being completely unmentioned in the documentation this appears
to be required to show up in the default programs UI on Windows 8.1.

Closes #1699.

These weren't merged from 2.1.9 with the rest of the file association
code, which results in the installer trying to reference nonexistent
resources and things breaking.

Updates #1699.

After shift-clicking on the grid the row to extend from doesn't equal
the active line, and clicking on the current active line to deselect all
other lines need to update the extend row.

Bumps 3.5 MB off the binary and doesn't seem to break anything.

We only ever feed UTF-8 to it, and it doesn't check whether the input is
UTF-8 before converting.

When launching Aegisub from Finder (but not via open), using the UTF-8
version of the locale breaks things for whatever reason, but fortunately
it's unneccesary as paths on OS X are always UTF-8 even if the locale
isn't.

Closes #1685.

Color matching to dummy video makes zero sense, and setting it to None
results in breakage when someone opens dummy video for an already
typeset script.

Closes #1690.

Newlines in the text are converted to \N, so no reason not to allow it
there.

Closes #1691.

FindExInfoBasic was added in Windows 7, not Vista.

--enable-stl replaces the implicit conversion to char/wchar_t* with one
to std::[w]string. This breaks conversions to boost::filesytem::path and
makes some ternaries ambiguous (which GCC helpfully reports as no
conversion existing rather than an ambiguous conversion).

Modifying the contents of a text control after IM processing happens in
the same cycle of the event loop seems to be seriously broken. Work
around this by disabling IM processing for time edits, as it should
never be relevant for them anyway.

Closes #1679. Closes #1680.

Move downloading the ICU data file to the ICU project, since that's the
only thing that was left.

Grabbing them from the package's src directory just adds another step
that needs to be done manually whenever a translation changes.

VS Express Edition doesn't support F#.
