ModelPaths: Update to 6.0 models

Used the file list from
http://www.zezula.net/en/casc/main.html

and converted it via a small Qt/C++ program, source at
http://pastebin.com/ETsvzWJm

Adds tons of new models. :)
Fix UnitPower triggers not working on initial log on

E.g. for me shadow orbs, runic power and monk's energy bar would
not correctly show up after logging in. Add the same event that is
used by stances to trigger all UnitPower related prototypes 0.5s
after login.
