Updated client to close any previous popups and bring up a new one.

NEEDS TO BE TESTED

Added delete on close

Server was using getMaxMessageCountPerInterval over
getMaxCommandCountPerInterval.

Raised command limit from 10 to 20

I have updated the `maxMessageCountPerInterval` from 10 to 15. This will
allow some faster play from exp users.

NOTE:
If you have an existing server and update to this version, you will need
to manually change the value in the ini file, or have no ini file to
begin with. Otherwise the old ini will load in 10.

add an empty room swell, if none had been defined in the config (or we
are running with no config at all)

and add a method to guess the path of servatrice.ini

Corrected tab to 4 space (per request)
Moved regonly option under authentication ini location (per request)

Implemented the ability to set the server to only allow registered
users.  Also updated client to reflect the log-in rejection as well as
put a check in place for the server to not start if db connection is not
available yet registration is required.
