Alternate skills bug fix

[bozimmerman]

This fixes a very annoying issue where Playerbot actions that specify a Spell, and an Alternate Spell, would fail outright if the first Spell was not available, and never try the Alternate.

Explanation: Part of what makes playerbots code portable between Zero and the other versions is that, when later expansions add new spells, you can give those more updated versions as defaults for certain situations, but keep the old Zero spell as an alternative if you are running the Zero server. Since I'm running the Zero server, I was seeing Playerbot failures to use those alternatives Constantly.

Thank you, and again, back at you!
If I saw correctly, many of the failed builds were because I dump so many PRs on you at once, causing your build service to reject them for using up the allotted time. My apologies: I like to playtest my changes for several weeks before showing them to anyone, and that causes them to 'build up'. I won't do it again.
