.cat domain breaks link detection

[harava]

The link detection doesn't work with .cat domains. For example, in the case of http://lol.cat/, it incorrectly detects it as http://lol.ca.

This also applies to some other sponsored top-level domains.

Yeah, the problem is that the regular expression which is used for URL matching (see here) is quite picky.

The "cat" domain would have to be added explicity; something like:

((((https?|ftp):\\/\\/)|www\\.)(([0-9]+\\.[0-9]+\\.[0-9]+\\.[0-9]+)|localhost|([a-zA-Z0-9\\-]+\\.)*[a-zA-Z0-9\\-]+\\.(com|net|org|info|biz|gov|name|edu|cat|[a-zA-Z][a-zA-Z]))(:[0-9]+)?((\\/|\\?)[^ \"]*[^ ,;\\.:\">)])?)|(spotify:[^ ]+:[^ ]+)

However I believe it would be better to rewrite this regex completely, as it is much too complex and by far doesn't cover all the existings domains nowadays anyway.

This is by the way a duplicate of issue #3.
