v.07

Getting close to the end of the Dare!

-Game now more intelligent of which tile you clicked on
-Tiles keep track of their neighbors
-You can now click on producing buildings to toggle production (useful
when you would rather somebody build a structure than harvest a farm)
-Added a Granary building, which provides +1 food per neighboring farm
every 3 days
-Added a win state: reach 100 population
-BUGFIX: no more ghostly tooltips when a tile is altered underneath the
mouse
-BUGFIX: fixed "-1 people starved" messages
