picstamp.fm -> picstamp.ss : removing `load' and usining units

Basic idea: the PIC18 support code is parameterized by: fosc, baud.
These need to be defined in the application unit.

The best approach seems to be to look at the toplevel app module as a
linker script that patches together different components, and provides
some "configuration modules".
