libass: ass_set_fonts_dir() is for a "private" storage place for fonts in case any of them need to be extracted.

Since we support fontconfig fontlookup on windows/mac/*nix there should be no real need to actually use this directory, but we still need to set one.

Originally in wrong order because of a blend bug that presented itself on fenrir's setup.

Recognized are
For macosx:
/System/Library/Fonts
/Library/Fonts
~/Library/Fonts

For windows:
C:\\windows\fonts
C:\\winnt\fonts

fontconfig: tell fontconfig about the fonts configdir on OSX ( /usr/X11/lib/X11/fonts ). There is no /etc/fonts

libass: move attachments processing before the ass_set_fonts_dir() option which enables those fonts.
Set a fonts_dir for OSX. We might wanna fix that later on.

Don't launch an update request at the first launch, but wait for the second launch in order to have the right network-policy value. This fixes the 'I update even when you said no" bug.

live555: fix "unpause" and remove startseq, which is no longer needed because we don't do NPT calculations ourselves.

kate decoder plugin: track and use basic formatting: region size/position, text markup - in particular, this allows image based subtitles to be scaled and moved to where they are meant to be if the accompanying video was encoded at a resolution different from the source
