Added part relative movement option (Shift+W by default), along with a move axis
Changed part rotation so it makes more sense, and displays the rotation axis arcs
Added rotation increment settings to buildmode (Shift+Brackets to change)
Added part rotation/position display
Expanded part move increment range down to 0.125
(NOTE: Red = X = Left/Right, Green = Y = Up/Down, Blue = Z = PgUp/PgDn)
(When rotating, keys are switched for X/Y because it feels better)
Made a bunch of build mode settings save/load (snap settings, move/rotation mode, and large/small thing)
Fixed dual-direction rotation sensor
Improved overdrive display in new UI
Fixed saw blade not working with logic inputs
Tread_collider now defaults everything to Slippery except tires
Fixed rotation snap so it actually does something reasonable instead of randomly rotating things
