Reimplement motor handling so the android application relies more heavily on the OR core ThrustCurveMotor class. This involved changing the database schema and querying mechanisms. Rewriting the thrust curve download logic in net.sf.openrocket.android.thrustcurve. Fixing the motor browser, motor details, and burn plot activities. The file parsing now uses the RSE and RSP parsers from OR core.

Browse Source 
ExtendedThrustCurveMotor class was created to hold the additional data required by the db ( the id in particular) along with the data which is useful to the browser (case info and impulse class).
