Merge pull request #29 from SoonDead/master

There is no need for double encode, but single quotes should be encoded.
use parse_url and a case insensitive regex to filter out any url (which has already been validated as a url) which uses the javascript scheme.
Merge branch 'master' of github.com:shakesoda/stepmania-site
These don't need a validator anymore, I think.
Adjust URL validator to not error on relative links (no scheme), hopefully fix quoting.
Add active state for nav (and remove outline)
