Move the ZTP hack to the game properties (reverted all changes from r6057 to the video plugins) due to some obvious reasons. Also some fixes to the coding style.

Remove a member variable which I introduced in r5907 although it never actually got used. Restores binary compatibility (at least in that regard) to pre-r5907 video plugins, but breaks any binaries after that :P

Update FIFO watermark tightness recommendations. 1000 is quite a high value I guess, but some people seem to need it.
