Title: IsItUp regex rewritten

To solve problems with IsItUp (pointed out [here](http://twitter.com/_0wl/status/199493176162131968) and [here](https://twitter.com/#!/ianchanning/status/200235196358983680)) I rewrote the regex for this Spice.

It uses simillar approach as #24 but also tries to check for a valid domain name.

Examples

is ideas.duckduckhack.com up
bbc.co.uk working?

But won't work for

bbc.ddg working?
duckduckgo up?
