Adds a preset for the 360, accounts for filters in the presets, updates manicure.rb formatting, removes from the presets the keyint stuff that's now handled in encx264.c, and slightly tweaks the x264 options of a few presets. Also, Animation and Television now use slower deinterlacing, and the latter uses weak denoising as well. Not sure why the @tv preset used trellis=2, brought that down to 1.
