Split config_storage.h into config_master.h and config_profile.h to

separate concerns and help reduce and clarify dependencies.

cfg and mcfg are too similarly named and are not obvious.  Renamed cfg
to currentProfile and mcfg to masterConfig.  This will increase source
code line length somewhat but that's ok; lines of code doing too much
are now easier to spot.
