Session also checks that strict session settings are enabled

Login class:
Automatic re-read of acl settings after some time (default 5min, can be chnaged via option).
Default set strict headers, can be turned off via option
Moved various parts into their own methods and cleaned up double call logic.

no more debug flags are read from the database anymore
All options are set via array and not with a single option (was auto login)
