Add a noddy game over screen that triggers when you end your turn
with 10 points or more. Menu object was enhanced to allow multi-
line questions to accomodate this.
UI improvements: Always use menu button to summon a menu screen,
add a status line that gives hints about controls etc, allow
using the B button as a shortcut for "Back" in menus that have
such an option
Also add a kind of "cheat mode" for testing that grants extra
resources
Refactor roads and settlements to abstract out some common features
and finish adding implementations of building roads and towns. Also
implement drawing a selection box around hex edges when choosing
where to build roads.
Refactor menu drawing to allow menus to customise how choices are
drawn. Make the trade menu more sensible to use, showing better
the trade costs. Implement simple 4 for 1 trading with the bank
