implement autobit and pinning in EDSP solver 'apt'

The parser creates a preferences as well as an extended states file
based on the EDSP scenario file, which isn't the most efficient way of
dealing with this as thes text files have to be parsed again by another
layer of the code, but it needs the least changes and works good enough
for now. The 'apt' solver is in the end just a test solver like dump.
