Added support for being effects through the eAthena levelup message, and check

whether the being exists before referencing it. Re-enabled proper MP bar
display. Improved handling of a warp to the same map.

(patch by Fate)

(cherry picked from eAthena client, the part about the levelup message
doesn't apply, and we now seem to have a second "effect manager"...)
