Delfador's "Teaching" ability should affect allied units

[cooljeanius]

@knyghtmare often proposes this idea for HttT, but Delfador is present here, too, so this could serve as a proof-of-concept for it

ok so after looking how UtBS does "Teaching" it looks like this will be a little bit more complicated than I thought; there's one macro for the ability, and then another for the events, so it's more than just a simple matter of plopping them in the unit definition... (also Delfador is created in multiple places, so...)

OK so that was actually simpler than I thought; fixed via 38e9208.

This would have been better if HttT also gave it to Delfador

well they still can! Think of this as like a "proof of concept" to help convince mainline to make the change, too.

...actually I'm going to reopen this, because in S15 Delfador is the only unit on his side, so the ability is useless to him. I'm going to want to modify the ability to allow it to apply to allied units (will require teaching myself more of the Lua API)
