Patch for new element types: formtable, formrow, name, address

I'm submitting this as a patch instead of just updating the code base out of the blue because it's been such a long time since we discussed folding the formtable module in, and because of the name & address fields, which are completely new. The address field includes functions for retrieving lists of countries and mailing states/provinces (currently US states only, but support for additional province lists is built-in.)
