Process URLs as clickable. Adds BUKKIT-4917
In Minecraft 1.7, URL processing was removed from the client while the
server gained the ability to designate a URL to be launched in response to
clicking text. However, this functionality is not implemented in the
vanilla server. This commit adds that functionality to messages sent to
the client, processing URLs as clickable.
Additionally, char array iteration is replaced with regex.
