Fix encBin check.

I am an idiot.
Get rid of sort dropdown in main interface.

It wasn't hooked up to anything and it doesn't even make sense to have
sorting as a part of the script. Aegisub has built-in sorting functions
that are faster and better.
Crunchatize Math.uuid.

Reintroduce origin.

Does NOT work with rotation, but appears to work with translation and
scale.
Add gitignore.
Linear mode settings are per-line.

Linear mode is now automatically disabled per-line if both pertinent
settings (origin and clip) are enabled and pertinent tags are present
in the line.
Version bump.
