WIP commit for UI drawing.

- Hooked up Diego's new Font API
- Added Style definitions for fonts, currently it uses
  a different font for panel titles to show it.
- Styles are in Userdef now too, still not finished 
- Userdef "DPI" will offer global control over font size,
  to match monitor size/resolution. It's meant to scale
  widgets and headers too btw, later.
- Lots of code removed for old fonts, but that's unfinished.

On todo: too much to mention, will continue happily tomorrow!
