[Setools] Gjallar settings contd.

I used a variety of settings and the autoLogin feature for debugging UI, 
so I thought that it would be useful to promote all the relevant 
settings into the ini file and Q2GjallarSettings interface.

component you are working on as root.

These settings are used in Q2Main initialize, which is called before 
starting the server.
