Does not allow dashes in hostnames

[fields]

Dashes are valid in hostnames. The latter part of the regexp in isAValidUrl? should be, at a minimum:

"//([[:alpha:][:digit:]-.]{2,})([.]{1})([[:alpha:]]{2,4})(/)")

(This should also probably be updated to include longer TLDs.)

Hi Adam,

Yes, this regexp is surely better.

This project is 4 years old and I've abandoned it for too long :)

I don't know how to do it on github (maybe changing the README.md like on some projects), but would you like to take the lead on this project?

Thanks a lot,

Alex

Possibly. Let me think about it. I suppose the other options is that no one will do it. :)

Still - I haven't found an alternative that's better, and this has been pretty useful for me.

On the topic at hand, I actually think regexps are a pretty poor way to validate uris, and we should probably use the built-in URI object now.
