Renabled the dynamic updates

The update host can be optionally received from the server in a
succesful login response or register response message.

This change also merged Subversion commits 4425 and 4426:

  Added support for handling the custom eAthena packet that sends the update
  host (patch by Sanga).
........
  r4426 | b_lindeijer | 2008-07-18 01:08:17 +0200 (Fri, 18 Jul 2008) | 3 lines

  Remove possible trailing slash at the end of the update host, since otherwise
  there'll be two of them.
