don't crash when fromNode is 0 for some reason

(it was a cyberdisk)
some code clean to remove warnings
frame skipping works

crashes were savegame related in fact...

only enabled in main battlescape state, for walking an shooting and stuff
.FLI intro plays, no music or sfx yet
FLI player for vs2010 proj
oh yeah, new files, duh
fixed HQX software mode, FLI plays in it but not 8bpp

of all the things, why would 8bpp software modes don't work
it's what the damn code is supposed to use in the first place
intro music is go
blindly added flx player to VS2008 project *shrug*
adding flx player to qmake file
ToggleTextButton for vs2008 and qmake files
whoops - fixing 8bpp modes
this is probably correct sync
pausing correctly on last frame (title screen)

pause timed for gmintro3 to lead into main menu music, at least with Vol's music files
forgot some shader files from a while back
intro sounds play but only with INTRO.CAT

SAMPLE3.CAT not supported at the moment because these files are a mess
resampling 8kHz samples to 11025Hz due to SDL bug
intro uses sounds from INTRO.CAT and SAMPLE3.CAT

remix?
fixing messed up SAMPLE3 sounds
gonna stop tweaking these sounds now :|
