[EXPLORER]

- Simplify the mess with the font handling in explorer. Make it respond to changes in the system metrics and use the correct fonts.
- Make CheckTrayWndPosition resize the taskbar based on the optimal size that the rebar returns.
- Without losing my sanity (yet), I managed to make it have exactly the same size as windows explorer when I run it in windows with the classic theme.
- Themes still aren't sized perfectly. Running on ros shows lots of bugs in our common controls.
