Project rename initial commit.

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.

Fix NPTest.pm not asking for unconfigured variables

It appeats STDERR isn't a tty anymore during tests, but since we type
from tty to STDIN it should be bound to our tty (and works for me).
New default installation prefix: /usr/local

Install into /usr/local instead of /usr/local/nagios by default, in
order to comply with the Filesystem Hierarchy Standard (FHS) and
presumably the expectations of most users.
