[Xymon] Xymon client with encryption + updated powershell client Windows

[Stef Coene]

Hi,

I created a github repo with my drop-in replacement for the xymon binary 
on Unix (tested on AIX & Linux) that uses wget or curl for communication.
This makes the data stream encrypted (https) and protected with username 
& password.

I also added a copy of the Windows client with some bugfixes and 
enhancement.
