Alpha 0.5.2

A small update to the game before we start working on the larger changes. This includes a lot of stuff that was suggested or mentioned in player feedback.

Changes:

• Updated the Crisis system tutorial to include information on the point needed to trigger a crisis going down with each crisis that occurs.
• Slightly increased cost of missions to counter it being made easier from the cost reduction techs working correctly now.
• Slightly weakened some of the T3 buildings.
• Slightly increased the time to arrive for earlier ships and slightly lowered the health as well.
• Added in a short general tutorial on how to play the game.
• Cooperative Endeavors now shows the points earned by it flying from one system to the other.
• Reduced Cooperative Endeavors from 5 Science/Exploration to 3
• Slightly increased the 'cost' of x2 points effects when generating a planet. Basically planets with it will have fewer points for extra slots, resources and points.
• Added the version number to the upper right of the game screen to make it clearer what version screenshots are from when issues are reported with them.
• Slightly adjusted screen layout to raise planets and keep the strategic resource display from going off screen on the largest planet size.

Fixes:

• Fixed an issue where cost reduction for exploration missions was instead increasing the cost.
• Fixed an issue with trying to build a 2 production cost building on a planet with a -2 production cost reduction effect.
• Fixed the Coordinated Targeting Center not working. 
• Fixed the Cooperative Endeavors bonus to correctly grant the mentioned points.
• Fixed an issue that prevented adding any buildings to a planet when at a negative for one of the  strategic resources rather than only preventing adding a building that requires that negative resource.
• Fixed the metal resource not showing up when reaching double digits of both water and biomass.
• Fixed an issue where returning to the menu and then trying to start a new game would leave the faction screen paused and unresponsive.
• Fixed the 'full game only' message showing up for the human faction when first entering the faction screen.
• Fixed spelling of a few words
• Fixed the warning when trying to build a wonder on an invalid spot to correctly say it requires a t3 instead of saying a t2 which was incorrect.
• Changing the building tier tab will also update the valid slots on held planets.
