Removed align enum from Alignment Box

It was causing issues in the VS designer.
Replaced usage of obslib.obs_align_type with ObsAlignment
Simplified AlignmentBox
Simplified even further.
Because I'm a programmer and i can complicate the fuck out of a ball bearing
Added Edit Transform Dialog >> TestTransform
Renamed AlignmentBox event handler to AlignmentChangedHandler / AlignmnetChanged
Added RotationBox event handler RotationChangedHandler / RotationChanged
Fixed new RotationBox default value not being 0
Lowered minimum size of RotationBox to 50;50
Added Tranform Edit Item to scene item rightclick menu
