• Bugfix FlxMenu, when using a fullpage question in a page with custom positioning, it would ignore it.
• Breaking Change, MPage.item_getCurrent() now returns MItem instead of MItemData
• Breaking Change, MPage.item_moveCursorTo() is now renamed to item_focus()
• NEW You can now declare an FlxMenu item to automatically get focus when the page comes in.
  When using FlxMenu.createPage add the special verb AF in the item string. (AF : AutoFocus)

e.g.

m.createPage("main","Main Menu").add("
	-|New Game   | link  | n_game  | D
	-|Connect    | link  | connect | AF
	-|Options    | link  | @options 
	-|Quit       | link  | id_quit | ?pop=Really?:Yes:No
");

^ Here the connect item will be focused first when the page comes in for the first time.

⚠️ : NOTE Still when a page goes back with @back it will always focus the item it came from
