Patch: Use an alternative to browscap

I normally use the script from http://detectmobilebrowsers.mobi/ to detect mobile browsers on my sites.

Here's a patch to use that script instead of browscap, if you're having trouble installing it, etc.

It's the first ever Drupal patch I submit, so be careful!

Regarding licensing note that while the code is open-sourced the developer is asking commercial sites to "Upgrade".
