[Xymon] New "test" for zone memory

Hi all

I recently cobbled together a "test", more to give me a single view of zone memory allocation than real alerting, and then I added the swap allocation too. More of a single view of all memory allocations and usage. It shows the caps in play, how much is being used, how much is available, and a few other bits and pieces, and can even alert if some go over threshold. I also threw in some graphing, which I find handy. YMMV

The code is a bit rough, and can do with a code review if anybody is interested. Constructive criticism is always well received.

It can be found here. https://wiki.xymonton.org/doku.php/monitors:zonemem
