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.
