Interface Updates

Did some cosmetic updates to the interface.

• Added shaders to the main viewport to give the map more depth
• Added outlines to the characters to have them stand out more from the background
• Changed the heat meter.

I think the changes make the overall game look much better.. more interface changes will happen as I go.

On a side note.. I have added building type updates to the game now.. Depending on the type of building will determine what type of recruits can be added.. :)
