check_nt patch for units problem.

[Alessandro Ren]

    I've noticed that if you use check_nt for check a COUNTER like this

./check_nt -H HOST-v COUNTER -l "\\Memory\Pages/sec","%.1f pages/sec" -w 
200 -c 400
17.0 pages/sec | '%.1f pages/sec'=17.000000%;200.000000;400.000000;

    the returning metric has this %.1f that pollute the data and gets 
showed in the graphics I generated, because perfparse storages it as the 
metric value, but if a issue the same command without the %.1f, it would 
return "No unit counter specified".
    So, I've patched the check_nt so it runs without the %.1f and it 
uses the description as metric. It returns as bellow, better in my opinion.

check_nt -H HOST -v COUNTER -l "\\Memory\Pages/sec","pages/sec" -w 200 
-c 400
pages/sec = 28.00 pages/sec | 
pages/sec=28.000000pages/sec;200.000000;400.000000;

it still works for normal % COUNTER checks, where it founds the % unit 
in the description field.

check_nt -H HOST -v COUNTER -l "\\Paging File(_Total)\% usage","paging 
file used" -w 95 -c 98
paging file used = 14.00 % | 'paging file 
used'=14.000000%;95.000000;98.000000;


    I am attaching the patch and I hope it does't break anything. I've 
made some tests and everything seems to work fine.
    I am attaching some graphics that generated by our capacity planning 
module that show why I made this patch and the patch it self made 
against nagios-plugins-1.4.2.

    []s.
