Create alias dilf -> mature_male/ mature -> mature_female

create alias dilf -> mature_male
create alias mature -> mature_female

To mirror the milf alias for the mature tag.

Thoughts on renaming mature into mature female?

I think it's a good idea, that way it stays in line with other tags. Besides, mature is ambiguous anyway.

Added alias.

We've gone from milf to mature and now to mature female. I can't wait for the day we decide that the word loli is no longer good enough and we need to call it preadolescent female or something.
