Micro AIs: check for existence of [micro_ai] tags in self.data when...

Browse source 
… setting up an MAI. Ideally, we would delete such previous occurrences
of [micro_ai] tags in the AI's self.data variable. However, the MAI can
be changed while it is not the AI's turn, when this is not possible. So
instead, we check for the existence of such tags and make sure we are
using a different ai_id.
