Reorganize Theme #148
Description
Reorganize Theme to include aditional informas such as:
- how should a default button look like
- how should the windows look like
This implies that for every Type enum from the controls there will be an Auto or Default variant that will translate as " what is the default for the current theme".
In the Theme object, we will be able to select what variants are OK / default for that particular theme (not just colors)
