Updated bspkrs' mods
Added additional return argument

Also added stripping of whitespace.
Added automatic deactivation of mods

Mods which fail to be polled a number of times, i.e. the version
information about the mod could not be retrieved several times in a row,
are now deactivated and put into a special list automatically. This list
can be looked up with the 'failedmods' command. Using the 'poll' command
on a mod removes it from the special list. A mod that has been put on
the automatic list can thus be activated until it fails the check a few
times again.
Added seperate rank restrictions for subcommands

Each subcommand can now have its own rank requirement. This allows you
to make the NEMP plugin available for many people, but keep the critical
parts of it restricted to OPs.
