Removed some un-used code from CVS. We can always resurrect this later if someone feels they want to work on it. Gone are the old perl ihost which isn't needed now, winhost which is broken and shows no sign of being fixed, and DBReporter. If someone wants to revive them, I'll undelete them :-)
Added URL to GPL headers.
i-scream is now licensed under the GPL. I've added the GPL headers to every source file, and put a full copy of the license in the appropriate places. I think I've covered everything. This is going to be a mad commit ;)
Decided to get the FreeBSD uptime/load information in a more sane manner. It's much quicker than parsing uptime, and more precise.
Solaris process accounting made me notice the number of times `uname` was being called. It was way over the top, especially as it's unlikely to change during an invocation of ihost :) Before it was run by each plugin every time they were run - in total 50 times a minute :/ Now, it's run once by ihost at startup, and that's it. The value read at startup is passed as a command line argument to each plugin. The plugins can fallback on working out the ostype using `uname` if they don't get given one on the command line.
Initial set of i-scream ihost plugins. These are derived completely from statgrab, and offer no new features over it. They do, however, allow for parts of this code to be replaced in other languages if required. Only a few minor changes were made, mainly for efficiency, commenting, and some changes of chop to chomp :)
