[s1891] Rename to new and clear defined tempsummon types

* Rename TEMPSUMMON_TIMED_DESPAWN_OUT_OF_COMBAT to TEMPSUMMON_TIMED_OOC_DESPAWN
* Rename TEMPSUMMON_TIMED_OR_DEAD_DESPAWN       to TEMPSUMMON_TIMED_OOC_OR_DEAD_DESPAWN
* Rename TEMPSUMMON_TIMED_OR_CORPSE_DESPAWN     to TEMPSUMMON_TIMED_OOC_OR_CORPSE_DESPAWN

You should not rename in Object.h nor in TemporarySummon.cpp
Also note that this rename will in the moment not change any behaviour; But the behaviour will then be like the name suggests!
