Small tweaks in the "findhost" web page

Hi Werner

	When I did the rewrite on bb-findhost.c (bbgen epoch), and if Henrik did not change to much, you can do what you'll doing the search as: "xxx.xxx.xxx.10$".

	The search field was intended do support full regex patterns. This is also the reason why you can search for multiple using host1|host2

	Sorry, I'm a little out off free time, so I could not be 100% sure, if this didn't change on v4-RCx versions.

Thanks a lot, I've tried several regexps and they all work.
