Michal Čihař - Gammu bug squashing

Gammu bug squashing

Today I decided to go through open Gammu bugs and try to fix some of them. There were trying many trivial bugs, which I'm now fixing, the harder ones will there stay for some other time or other volunteer (feel free to take some!).

There are still some issues remaining, but I will go through rest today and tomorrow and make testing release after that. So far ChangeLog length looks quite impressive :-).
