Alpha 0.2.1

A small patch to fix a few more issues after the last one. See the full changelog below.

Changes:

• Changed some of the default tooltips into better looking tooltips. 
• Removed the shadow that was showing behind some tooltips.
• Added a bit of text shadowing to the point numbers on planets to make the text easier to see on lighter colored planets. 
• Reduced the amount of shadowing on the Lock Selections/End Turn button as it seemed a bit strong.

Fixes:

• Fixed the Scout Squadron not being properly positioned in its slot.
• Fixed an issue that prevented the player from building on a planet returned by blockade after the planet selection phase.
• Took Crisis Center back out of the starting buildings. It was accidentally left in after testing the fix for it in the last build.
• Fixed an issue with two of the tech nodes in the tree that caused them to not provide their bonuses.
• Fixed and issue that caused Pirates to not return their production when hit.
