Tidying up various things:

Made the support library contain only the xxxRecord and device support,
then renamed _APPNAME_Support.dbd to xxxSupport.dbd to reflect this.
Actually I should rename the library to libxxxSupport, but I didn't yet.

Now we link the dbSubExample.o code directly to the application,
renamed the registrar routine inside this to mySubRegistrar,
and also moved the registrar() dbd entry into _APPNAME_Include.dbd.
