Title: fix new warnings on GCC 4.7.0

Work started by @robn.

This doesn't do anything clever; mostly the warnings have been fixed by explicit conversions.

The `Color` type has been renamed to `Color4f`, with a `typedef Color4f Color` to make it accessible under its previous name. `Color4ub` has been added, with a conversion from `Color4f` -> `Color4ub` (this is used in GuiGradient, but currently nowhere else).
