[Xymon] Xymon 4.3.29 scheduling and F30

Hi all,

Just to give everyone an update, I have a few more patches I'm still looking at, but I mostly wanted to wait until I get a chance to test compile fixes on Fedora 30 final, which should drop today or tomorrow.

There are still a number of compile warnings generally (mostly char mismatch warnings), but if you know of compile issues on other platforms specifically, it would be helpful if you could run a quick test on the latest 4.3.29 snapshot to see if it's resolved. The latest snap is available at https://sourceforge.net/p/xymon/code/HEAD/tree/branches/4.3.29/ in the upper right.

Thanks, -jc
