Pre-release 2

Adjusted more values for balance

Removed time delay, now science gained just reduces every time you analyze (first three times is unhindered).
Added a "scienceDecayScalar". Removed all the time-delay readouts and such.

As of this commit, the scalar for science returned is calculated by:

science * bodyScalar * scienceDecayScalar

where scienceDecayScalar is y = 1.20^(-0.9*(x-2)) (where x < 2, y= 1)

Changed the "TURN LEFT" and "TURN RIGHT" to rover.heading > rover.bearingToScienceSpot. This should make the instruction more accurate, and less likely to jump everywhere.

Moved part techRequired to fieldScience where the first rover wheels appear
