* readPanel(): reading potM and potD as analog inputs.
* loop(): - Make up for DEBUG_MODE.
New enum type: autoModeStage.
* Changed data type for	stage from int to a group of const short.
* goToTheInitialPosition() was commented.
* applyAutoMode was reimplemented.
* New function: moveCylinderUntilHighPressureBecomes().
* Moved to another place in the code: moveBothCylinderDuring().
* New function: releasePressureManualMode().
* Adding high pressure protection to SOLU.
* New function: getOppositeSolenoid().
* moveCylinderUntilHighPressure() now release the pressure before return.
* Renamed VALUE_HIGH_PRESSURE_ to VALUE_HP_
* Renamed VALUE_SOLENOIDS_ to VALUE_SOL_ .
* Added substage support.
* applyAutoMode(): added substage support to FAILSAFE_STAGE case.
* udpateLeds(): Updated implementation for manual mode.
* moveCylinderUntilHighPressure():
  - now returns void.
  - replaced the while loop whith an if.
* applyAutoMode():
  - Replaced calls to moveCylinderUntilHighPressure with moveCylinderUntilHighPressureBecomes() when we want to get times.
  - Now enabling the LED_STATUS when taking times.
* applyAutoMode: Reviewed the algorithm to make it fit with the new moveCylinderUntilHighPressure().
