For Sale, Trade, etc drop downs in classifieds

[dixie_boysles]

Tom, we need drop downs when making a new ad for SOLD, FOR SALE, TRADE, EBAY/CL Finds...etc

[Tom]

Added dropdown for new thread postings: for sale, want to buy, for trade, craigslist/ebay finds.

The "SOLD" modification is more complex so that will come later.
