First release of the bruteforcer.

To-do list:
Handling of multiple servers.
More ways to acquire usernames (currently only possible on sites that print usernames as "<td>user_name</td>"
Acquiring usernames from external sites. Most of them are not updated live, so that might be a problem.
New ways of bruteforcing.
