UDMF Controls plugin:

Relative mode is set to false by default.
Limits of Brightness slider were set after setting it's value, so values greater than 100 were set to 100.
Fixed a bug when a plugin tried to access 3d-floor-specific stuff of walls, which weren't part of 3d-floor.

Color Picker plugin: added float representation of current color (like 1.0 0.54 0.29). Should make editing of GLDEFS light definitions easier.
