v0.1.2

Made a package repository (see instructions in this repo's readme for how to install, instead of using unitypackage you install from this git repo). This should make updating much easier as you just press a button. (suggested by Haz)

Also:

• point lights will be the correct scale (ty to TroyBORG)
• fixed icon so it says exporter not importer
• Supports positional constraints. Uses RelativePositioner component if you have one source with weight 1 and "freeze axes" enabled on all axes. Otherwise, automatically generates some flux and dynvars that support all other configurations (multiple sources, a subset of axes, etc.) (ty to Venport for suggesting)
• properly grabs dependency slots of constraint sources even if they are outside selected hierarchy
• removed some unneeded dependency dlls from the unity package
