#1 Patches enabling HostMib hrProcessorLoad support

[Russell Adams]

These patches add a separate module to discover
hrProcessorLoad (tested against Win2k and Win2k3 hosts).

They ought to be rolled into the main HostMIB module.

The discovery process for the processors requires
searching the
entirety of the hrDevices table for Processor entries.
They may be
consecutively numbered, but they are not in a fixed
location. The code
works around both cases.

Two multigraphs are creates for multicpu systems, one
with an upper
limit (cpus*100), the other allowed to dynamically
scale. Single
processor datasources are hidden if there are multiple
cpus.

I also included my override template for long term RRA
storage. I need
to look into how to force it to be the default for my
installation.
