Custom Region Coloring

Users can now define custom color and/or opacity settings for their region types (or individual regions). 
These settings are found on the Region Type config page or on the map itself (config icon on the appropriate region type's data tab). 
The color option includes the ability to enable or disable custom coloring for the given type; given that coloring is enabled, 
the user may define a custom color and/or cusotm opacity for all regions of this type. The user is also given the option to 
enable or disbale child override, so that any individual regions with custom color or opacity settings will override the type's settings. 
If the child override is disabled the individual regions will be rendered according to the color settings of their parent 
type even if their individual settings have been set.
