Update thruster performance tests.

[andytorrestb]

The following testcase: mission_integration_test_01.py should be updated so that thruster performance calculations are compared versus expected values using thruster ID values, not index values.

Expected values can be hard corded into the script using results from hand calculations. Each thruster should have the following data checked.

1. Thruster Position Vector
2. Thruster Normal Vector (which direction is it pointing)?
3. Thruster Force Vector
4. Thruster Normal Arm
