Open Route 31, Violet City and Sprout Tower (#31)

Enable Route 31 and its gate, Dark Cave's Violet entrance, Violet City with its buildings and Sprout Tower. Port the script commands they use: gettrainername, askforphonenumber (with AddPhoneNumber's room for Mom and Elm; addcellnum now reports failure as the original does), checkpokemail, loadmenu/_2dmenu/closewindow, giveegg and trade (NPCTrade, with wTradeFlags saved).

Eggs keep their species with an egg flag, as wPartySpecies does. The pack's TM/HM counts receive, check and toss TMs and HMs, which are named TM01-HM07.

The playthrough continues through Route 31 (with Mom's call), Violet City and Sprout Tower to Elder Li's Flash.
