add nant startServerBackground to have a non blocking start of the server.
add --nonstop to fix problem with nightlydevzip.
delete some Mono dlls if the server (and later server admin) is started with Mono on Linux.
nightlydevzip: start Server in the background.
use smaller demo database.
make sure initConfigFiles is called before starting the server admin console.
ServerAdminConsole: exit with error if something did not work.
this helps with nightlydevzip, load demo database. nant devzip should fail if database was not loaded.
