LadokAD support

Added 3 libraries ..adladok.test, ..adladok.model ..adladok.xmlaparser
and one library for connecting to web service. (Perhaps could this
library be smaller i took the verbose version I think.) Added
AdLadokTest to Manifest so this part can be tested.
In my Model there is the classes Me (Static) and Course (same name as
one of the other classes in the project. These files should perhaps be
merged?
Function
The Me class does everything on an asynctask and notifies any listeners
via an Listener pattern.
