Fork VCMDecoderDatabase for VideoReceiver.

Browse Source 
This is to keep the deprecated VideoReceiver separate from the
implementation used by VideoReceiver2 before updating
VCMDecoderDatabase to have ownership of the registered decoders.

Fixing typo (DataBase->Database) in the name of the remaining class.
