Add more reports / integrate logs with views

I added a page to my PHPIDS module that displays the entries in the watchdog table for PHPIDS grouped by `hostname` and the number of entries from that host. It also resolves the IP addresses to hostnames which makes identifying bots easy. I will probably add some other things to it in the future, but for now I've attached a patch that adds this functionality for the 6.x-1.x branch. I've looked at the coded and the 6.x-2.x branch look pretty similar so the patch may not work but the same code should work.
