NRPE_NT Code

Command script should have DOS line breaks

Removed support for building with MSVC.

Added suitable svn:ignore attributes.

Renamed INSTALL to INSTALL.nrpe, because the name INSTALL is used by
Autotools.

Reverted last commit for this file; by mistake.

Apparently AM_PROG_CC_C_O is required these days.

plugins/wts_load/Makefile no longer exists, with new VBS based implementation

* Replaced the wts_load.exe with and WMI script to gather the
information from teh server, this is because the API used may
be changed and not be available in future and wts_load.exe
fails on Win2008R2 due to changes in API.

* Included wts_load.vbs in packaging and added a section in
nrpe.cfg describing the usage.

Files in doc has been moved to sourcetree root,
updated the project file to reflect the changes.

Source has actually been broken for several years:
It has subtracted the used RAM from the used page file without
accounting for the non paged RAM. This may lead to negative numbers,
often directly after reboot. Solve by subtract the non paged RAM, if
we can get it, and make sure that the used swap is not negative.
