[8548] implement db supported battleground eventindexes

those eventindexes will then be used by the battleground-code to decide
which creature belongs to which objective
for example all creatures in alteracvalley which are standing around a tower
will belong to one eventindex then.. the eventindex will be defined through the code
and must be proper documented for db-devs
