Start delay compensation

It allows for setting offsets to a fixed-time event to compensate the time needed for reaction of the hardware. The offsets may be:

-During play or pause mode- tries to compensate for the time (in milliseconds), necessary for executing commands like Jump, Next, and Resume.

-During stop mode – tries to compensate for the time, necessary for executing the Play command.

NOTE: These settings are hardware-specific, so their exact values have to be determined experimentally.

WARNING! When using fixed-time events, the playlist should start and end within the same calendar day (i.e., the playlist should not go beyond midnight). Otherwise, we cannot guarantee the proper operation of the fixed-time logic and that of the daily playlist logic.
