Analog pin bugfixes

This is a bugfix release to resolve a regression involving the analog pin numbers in 1.1.3 - the pin names of the form A# would all read pin A0, regardless of which pin name was used. This has been resolved, and all A# pin names now work.

This also fixes an issue with printing strings from flash using the F() macro, programming the attiny167, and use of "ponyserial" type programmers.
