[settings] - add new expert setting for enabling ios8 compatibility
[airplay] - implement different announcements when using the ios8 compatibility mode
[airplay] - implemented photo asset cache
[airplay] - send an error code for the fp-setup request
[airplay] - add some handy helpers for using binary plists
[airplay] - handle /play of newer airplay protocols - instead of location it sends 2 seperate entries host + path
[airplay] - merge the binary plist and xml plist pathes in airplay (which already diverged) by using libplist for parsing in both cases - not only the binary case
[airplay] - support the /play command which wants us to start playback "paused" - (camera roll on ios8 for example)
[ExternalPlayer] - reset m_time on openfile (fixes bad playcount marking
on successive played movies)
Dialog: Don't reset symbol keys after onClickButton

* Resetting the keys makes typing a URL, SMB, FTP or any address
    a longer process than is necessary, especially with a remote.

[vobsub] Fix for incorrect colours with vobsubs and GLES

Fixes #15146

The code provides the overlay texture in BGRA format, which it informs GL about.
However GLES does not support BGRA, and just claims it is RGBA which results in a red/blue swap.

So this code path needs a red/blue swap.
Don't get the progress handle if we don't have the progress dialog when scanning music
