refactored method name to common style, added another debug message for parameter parsing
added two parameters to the command line options, --nogui and --password=<password>
- password is used in getCurrentPassword
- nogui is not used

getCurrentUname()
- now always returns the command line user name in order to override the thing thats written in the gui

reformatted debugging print outs

undefined the debug options again, forgot that on the last commit
finished refactoring the debug printouts for sshmasterconnection and onmainwindow.

undefine'd the DEBUG flags again.
