Removes kmcomp.dpr, related source, compilekeymanweb.pas, and related
unit tests.
Cleans up a couple of bits and pieces around kmc in order to help tests
to pass, and updates some tests that had legacy code in them
(particularly missing &TARGETS stores).
Removes all references to source .keyboard_info and .model_info files in
the kmc compiler and types. Updates the model info compiler to support
building purely from model sources (isRTL, license fields are TODO).
