Disambiguate AoSoL's Punt skill

[ziz]

Description

AoSoL's Punt is 28021, which autoscend supports. WereProfessor added a Punt skill number 7510 (support was added in Mafia r27841), so now mafia throws multiple skill match warnings.

Adding [7510]Punt (duplicating the [28021]Punt use, more or less) to auto_combat_util.ash would make sense if autoscend is expected to eventually handle WereProfessor, but that's more than just a trivial warning-removal fix.

How Has This Been Tested?

Before patch, importing autoscend.ash gives

After patch, these warnings are gone.
