Increase number of players allowed in embedded server / customize server

[palotian]

Jamtaba server only allows 4 players to connect and play simultaneosly, although more players could be necesary for certain works.

8 players is my current personal need triggering this request, but jamtaba could offer more flexibility.

On top of that, an additional option to customize some features of the Jamtaba server (above mentioned number of players and server topic / welcome line) would be a real plus.

A drop list offering a range of options for the max users quantity and a text box for the topic in the "Hosting Ninjam Private Server" dialog would do the job.

Thanks!!!
