Add libass cflags to subtitles_provider.o
Remove the border around the video box in the detached video dialog
Add some padding between the video box textctrls
Remove calls to SetBackgroundStyle(wxBG_STYLE_COLOUR)

With wx2.9 it's a no-op.
Calculate the required size for the subs edit box time edits rather than hardcoding it
Actually stretch the volume/zoom link button
Remove the "update video" box from the find dialog

It hasn't worked for a few years and doesn't really make any sense with
how committing works now.
Delete worthless comments
Shuffle around the find dialog sizers to cut down on empty space
Eliminate some duplicated code in the find dialog
Remove an unused variable and rename a misleading one
Use enums rather than magic numbers
Fix loading unicode actor names from plain text files

'isComment ? "" : actor' results in actor decaying to a const char * in
the local charset rather than converting "" to wxString, which breaks
things when unicode is involved.
Fix compilation with clang
Move the SearchReplaceEngine instance to the context
Use STL names for wxString functions with a bunch of aliases
Decouple SearchReplaceEngine from DialogSearchReplace
Rewrite SearchReplaceEngine

Decouple it from the subtitles grid and do everything through the
project context instead.

Actually obey the "In Selection" option for things other than Replace
All.

Cut down on the amount of logic duplicated between Replace All and
normal find/replace.

Start searching from the current cursor position, rather than the last
found position.
Add option to skip comments in the find/replace dialog. Updates #683.
Add an option to skip override tags when searching. Closes #104.
