Bugfix:
 * Stop and Play not working when track is finished
 * TorqueScript virtuoseStart: deleted the orchestrator.setTempo(90)
FIX MAJOR ISSUE IN TEMPO MANAGEMENT + project release mode optimisation + add glockenspiel fxp
 * Sequencer now waits a fixed and integer amount of time between each tick incrementation
 * Ticks are incremented by a value function of the tempo and the number of ticks per quarter note
 * Major issue was that we tried to wait less than a millisecond or during a floating amount of time, which is not allowed
   by the system. So it lead to incorrect tempo.
 * See Sequencer::computeTickStep() and Sequencer::run()
