Morph targets blend in the viewer: cloth waves

35 left morphs out: the viewer played rigid and clump animations but did not apply F_Morpher records.

Each Morpher chunk names a base model. When a job's own animation has a morph track for that morpher, playback does the following at every game frame:

• takes the last F_Morpher record at or before the frame (its targets and weights);
• blends each of the base's mmats with the matching mmat of every target through anim::morph, the integer ccMorpher::Modify of 32;
• places the result instead of the stored positions.

A file with morph animations now plays the first one by default, the way a file with bone models always has.

xp_flag is a flag whose cloth is two morph targets. It waves: 63,546 bytes of a 480 x 360 shot change between 0 and 0.5 seconds, and morph_cloth_plays checks that its vertices move between game frames 1 and 15.
