Zack Middleton e4208cf5a7 Improve finding obelisk entitynum for bot AI 
BotSetEntityNumForGoal() was checking all entities that are not
team_redobelisk (which is the obelisk visual entity) to find the
untitled obelisk collision entity. This may fail in rare cases where
there is an another entity within 10 units of the obelisk origin.
Failing to find the correct entity may cause bots to not attack the
obelisk.

Instead add BotSetEntityNumForGoalWithActivator() for looking for the
obelisk collision entity by activator classname (team_redobelisk) which
should be less likely to find the wrong entity.

This doesn't affect official Team Arena maps (unknown if it affects any
others).

Reversed strcmp check was reported by Thomas Köppe.
