Multiple fixes...

1. CPRadio should not draw its background color by default when created from a nib.

2. Substituted named constants for magic number bit flags.

3. Don't set the matrix view background color unless the nib said to draw its background.

4. NIB_CONNECTION_EQUIVALENCY_TABLE wants UIDs, changed self -> [self UID].
