Add dump commandHEADmastermain

This command dumps the modem state to a file. The modem state is
retrieved with <AT COMMAND>?.

The Python configfile format was chosen as it's human readable and it
might also look familiar to store data as it's also used by Gammu to
store SMS.

Having an (SQLite) database intead would prevent easy comparison
between files with software like diff or Meld.
