[Xymon] Feature requests, combo.d, uptime alert, xymonserver.cfg syncing

• combo.d directory for combo includes. Helps to organize.
• uptime configurable to be a red alert. Quite often a machine can reboot quickly and we can be unaware for some time, we would like to be alerted so we can restart all application processes ASAP to minimize downtime.

From xymond_client.c:

if (cpucolor == COL_GREEN) cpucolor = COL_YELLOW;
addtobuffer(upmsg, "&yellow Machine recently rebooted\n");

• TEST2RDD and GRAPHS variables moved to another file, perhaps an include for xymonserver.cfg? Why do I ask because we have dual Xymon servers running for redundancy and it would be nice if I could easily rsync these 2 variables in a file that does not have host specific variables. Currently I cannot rsync xymonserver.cfg because of the XYMONSERVERHOSTNAME, XYMONSERVERIP, XYMONSERVERWWWNAME variables.

For the last one I am probably going to copy xymonserver.cfg to the second server and diff the files for anything but the 3 variables above and to send an alert to remind the person who made the GRAPHS and TEST2RDD changes to update the other server.

As always thanks for the great work!
