Added an acronym FAQ and AA recommendations

Today I have added a FAQ with a glossary of acronyms that I hope will be useful to new players. I plan to add to this as other terms come to mind.

I also added a list of recommendations for AAs under Skills which again I hope will be useful to players. Because there are a lot of opinions about which AAs to learn first I have written it more as a breakdown of key AAs, and it is not intended to specify a specific order.
