  AI helper: improve efficiency of get_unit functions

The old method is very slightly faster in some circumstances (e.g. for
simple filters and when all units have moves/attacks/etc. left), but we
are talking fractions of micro seconds. By contrast, depending on the
filter used, the new method can save large amounts of evaluation time
once some units have move or attacked.

  Goto Micro AI: change order of SLF and SUF evaluation

This is for efficiency reasons, as location filters do not necessarily
change throughout a side’s turn, while fewer and fewer units have moves
left.

  Goto Micro AI: add [and] to a filter

Another efficiency improvement.  This ensures that the side of the unit
is checked first before the potentially complex rest of the filter is
evaluated.
