Feature pic12bootloader

I updated the MIB code to not send parameter headers like we discussed.  I have the change done on pic12.  The pic24 code needs to be ported over to work with the new way of building parameter sets.  There's an example in controller_mib_feature.c and the new macros are in protocol.h

@amcgee - Could you do the pic24 side of the changes.  I'm working on making sure the pic12 mib code works with the new way.
