<MSG> * have common base classes for cgeo related activities to encapsulate
the related code
* move several methods from base to the activities classes
* remove all duplicated goHome(), goManual() methods
* remove instance variable "activity", which is only a this-pointer
(all triggered by issue #98)

If you have trouble merging afterwards, I'm happy to help.
