Resolves #2089.
Partly resolves #2087, #2088. This was happening because scratch-vm is responsible for timed motor commands rather than using the Boost hubs commands to run motors for a specific amount of time. This meant that when we simply sent a motorOn-command, the hub would immediately return feedback for the motor that the command had completed. The fix for this was, for timed motor commands, to not receive feedback from the motor, and instead have scratch-vm modify the BoostMotor._status. TODO: Fix for rotation-based commands. Agreed. Changed to 50%. - BoostMotorMaxPower changed to BoostMotorMaxPowerAdd and now describes an extra boost (no pun intended) to the motor. Documentation added that describes the feature. - _colorBucket renamed to _colorSamples for clarity. - oldColor is renamed to previousColor, and is now initialized in this._sensors. - Modified documentation.
