Added a time shift parameter for each transition type (except dissolve): as if the transition had already been in progress for some time by the moment of its start.
Updated test script to show new behaviour.

To fix typo in blink function and not affecting existing projects a blinkContinuous function was added.

Added blinkContinuous function

To provide more natural behaviour onPause call was added in case if time shifted transition has delay. onPause called after one execution of object`s parameter recalculation which performs even if time shifted transition has delay and only after that thansition waits for delay ms. So there is some kind of pause happens.
