  -----------
  Some cleanup to the unit frame code

Explanations:
- Removed all the redundant constructor initializers
- Don't initialize the color members.
  (Otherwise what's the point of it being an optional?)
- Some collapsing of stuff like ? true : false and similar cases
- Use operator* and operator-> instead of get() for optionals
-
