Healer Support MAI: switch to using external CAs

history, if needed.
Both Recruiting MAIs: switch to using external CAs

This includes disabling the rush recruiter for the time being, as the
engine files it uses do not yet use the external CAs.  It will be
re-enabled once those have been converted as well.
Recruiting MAIs: get rid of recruiting_type= key

The previous value of recruiting_type= now goes directly into ai_type=.

All Micro AIs have now been converted to using external CAs.
[micro_ai] tag: remove now unneeded code and comment
Micro AIs: remove all the MAI engine macros

They are not needed any more now that all MAIs were switched to using
external CAs.  For the time being, we keep the macros in place, but
they now only display deprecation messages and have no actual
functionality.
Fix some indenting in AI recruiting functions
MAI engine deprecation macro: add side=1 to dummy unit

This will be ignored since the [unit] tag is used inside a [side[ tag,
