Reduced the length of shadow roads to remove improper road selection
when clicking right on a road intersection
Reworked structure labels to display text better and to be more scalable
Minor fixes related to rebase
First iteration of delivery detection and point assignment
The game detects when all deliveries have been made and will display
a win screen
Added fuel consumption to game, as well as refueling and HUD
elements that indicate fuel status and cash accrued.

Currently the solution is highly unscalable and will need
much more work
Changes made:

   * Fuel Stations now cost Cash and fill up the vehicle based on
     how much fuel the player can afford
   * Fuel cost takes difficulty level into account
   * Fuel consumption is tracked per "tick", letting players see
     a reduction in their fuel gauge while en-route to their
     destination. This also allows the game to end as soon as the
     player runs out of fuel, in the middle of a journey.
   * Added custom message for Fuel Stations that let the player know
     how much fuel costs per "tick"
   * Once visited, delivery locations show a "Delivered" message in
     place of the Cash that delivery was worth
Minor cleanup for merge.

Also changed the look of the fuel gauge on the HUD and added color
to visually represent when the vehicle's fuel gets low.
Major HUD re-workings.
Major changes to road highlights. They now show the direction the
vehicle will travel to give the player a better indication of where
they are going to go.

The highlights also show up when hovering over a road that is a valid
selection for the next destination.
Final commit for Alpha 1.0!

More major changes:
 * Added fuel needle to HUD and made it rotate based on fuel consumption
 * Reworked the road highlights to be one solid color and display the
   number of times the vehicle will drive in that direction near the
   highlight. This makes it more explicit and obvious how many times the
   player has clicked on the road
 * Made the fraction text better aligned when double digits are displayed
 * Removed placeholder images that were found on the Internet to avoid
   legal issues for distributing the Alpha version
