Defaults: Change default axes for Track To constraint

The main use-case for the Track To constraint is camera tracking, so
this sets up a better default for this. That is, track to -Z with Y up.

Agreed on internally with Pablo Vazquez and William Reynish. Should
there be a reason to revert this, that would be fine compatibility-wise.
