This is an initial take at renaming the project to Monitoring Plugins.
It's not expected to be fully complete, and it is expected to break
things (The perl module for instance). More testing will be required
before this goes mainline.
If Perl's "shift" function is called outside of a subroutine and without
any argument, it usually shifts @ARGV. However, if a plugin is executed
via ePN, such a call will shift @_ instead, so we must explicitly
specify @ARGV for this to work as expected.
This fixes Debian bug #545940, see: http://bugs.debian.org/545940
Commit de7191e342 fixed the same issue for
check_disk_smb.
