Nut upsdev - Feb 2011 - [PATCH] add support for more Matrix-UPS revisions

As I requested here:

https://bugzilla.redhat.com/show_bug.cgi?id=678793

Add support for Matrix-UPS firmware 0XM/0XI with additional commands

Description of problem:

The attached patch adds support for Matrix-UPS revision strings 0XI 
and 0XM to the apcsmart driver.

The revision string itself isn't completely opaque--it is made up of 
different parts as documented on 
http://homepage1.nifty.com/Que/plamo/apc-ups/manual/upsbible.html 
under "Old Firmware Revision".  This implies that many more 
combinations of characters could be added to support more revisions & 
configurations.  Indeed, 0XI and 0XM only differ by the placement of 
the 208V/240V input voltage select wire.

The first character can be 0 or 5 for Matrix-UPS 3000 vs. Matrix-UPS 
5000.  The second character is the actual firmware revision.  I've 
read in various forums about revisions U, W, X, Y, and Z.  There is 
probably a V as well.  The last character seems to be I for 240V and M 
for 208V, which I can change on mine by the placement of the input 
voltage select wire.

I've also tested the expanded command list which enables nut to access 
more functionality on my Matrix-UPS 3000.  I suggest that this same 
expanded list could be applied to all the other firmware combinations 
as well.

Please consider adding at least this patch which is limited to 0XI/0XM
initially.

Thanks,
Chuck
