RTS-prototype take 2

A small attempt at making a simple real time strategy. UI design is not my strong suit.

Start with 6 workers. Can instruct them to build a building or collect resources. 

Currently no combat, will potentially be implemented later

Use <A,W,S,D> to move the 'camera' around the map.

Select units by left clicking on them individually or left clicking and dragging to select multiple. Select destination by right clicking. Deselect by left clicking empty space.

When worker is selected, can assign to a resource (gray circles) or select a building to build is the options pane on the right.

Buildings can only be built in the area of influence of a stock-pile (blue diamonds). An initial stock pile is already built but you can build more. buildings must be build at least 1 tile away from resources and other buildings

clicking on a building provides construction options and displays the amount of resources it holds. stock-piles can build workers, test-buildings can build workers and transports.

Transports move between stock-piles. They are intended to move resources to other stock-piles but currently only just travel between the two stock piles without exchanging resources. A known bug causes game to crash when a worker tries to drop off resources to a stock-pile that a transport is heading to.
