Removed obsolete version of Int36 (using signed integers internally); sticking with unsigned integers internally not only simplifies some of the existing logic, but will make it easier to add logical operations later (eg, AND, OR, XOR, etc)

Trying a second approach to the Int36 class that sticks to unsigned numbers internally (only downside so far is that the detecting arithmetic overflow/underflow is more work and hasn't been implemented yet)
