release 3.0
Some major language changes have happened in this 3.0 release:
- cpu register variables (A, X, Y) are gone. It's no longer possible to directly access cpu registers from prog8 code -- use inline assembly if you need it
- repeat-until loop changed to do-until
- introduced repeat X {} loop as a more optimized for loop of sorts where you don't need the iteration variable
- forever {} loop is gone, it is replaced by repeat loop without iteration count.
