Fixed some imports, missing stubs
Fixed spacing issue
use power instead of hardcoded energy
Use VComp, instead of incorrect HComp
Fixed a sign bug in BOTTOM->BOTTOM anchor code
Tweaked maxCast position
Added Mapper, for list transformations
Fixed Group's InsertInto when using Map

It's necessary to clone the GuildMember for insertions, but MapValues
may return a non-GuildMember value. I went with a conservative option,
only cloning GuildMembers that we've created, and letting everything
else pass by unmodified.
Groups now errors if given an unknown group name
Fixed a misplaced assertion
Added Frames.Saturate, Desaturate
LuaEnvironment gives better errors when files failed to load
Added alias in Icon
Checkbox no longer inherits Icon (since there's no need)
ApplyStandardButton checks with method names, rather than GetObjectType
Serious cleanup in Media-Texture

This may have broken some old texture names, so suspect this commit if
you have broken textures.
Prefer Anchors.ShareAll even with buttons
Support overriding blendModes in Frames.Texture
Added a couple methods for setting Frame width and height
Added assertion to GetAnchorArguments
