check_nwstat: adds percentage used space (#1183)

Browse source 
* check_nwstat: adds percentage used space

This adds the new VPU parameter to the check_nwstat plugin.
This parameter returns the percentage used space on a Netware volume.
Now you can monitor your Netware volumes easy. We use it with a warning
85% and critical 90%.
eg: check_nwstat -H your.netware.host -v VPUvol1 -c 85 -w 90 returns
324653 MB (95%) used on volume vol1 - total 340212 MB|Used space in percent
on vol1=95;90;80;0;100.

* check_nwstat: Fixing whitespaces and tabs

* Update translation files

* check_nwstat: Use C99 booleans also with the patch

* Some formatting
