Quick Bug Fixes/Balancing

When I first uploaded the demo last night it was very impulsive and I overlooked certain aspects of the game. So to better convey the overall concept I'm going for,  I changed the gameplay balance a bit.

Changelog:

• Added max populations to  colonies based on their habitability score
• Science is generated a bit slower
• Balanced upgrade scale cost
• Reduced the starting number of foundable colonies 
• Colony technology now increases number of foundable colonies by 3 instead of 2
