Delayed StepKeyframe

From Omtwiki

Meant to provide some little extra usability from the ',' and '.' hotkeys by doing playback when you holding down the keys.. and stopping on release Kinda testing still.

Use it by making 4 new hotkeys with the following name commands:

nextKeyDelayed_press:

 python("import OMT_hk_delayedStepKeyframe");
 python("OMT_hk_delayedStepKeyframe.onPress(True)");

nextKeyDelayed_release:

 python("OMT_hk_delayedStepKeyframe.onRelease(True)");

prevKeyDelayed_press:

 python("import OMT_hk_delayedStepKeyframe");
 python("OMT_hk_delayedStepKeyframe.onPress(False)");

prevKeyDelayed_release:

 python("OMT_hk_delayedStepKeyframe.onRelease(False)");

Map the two 'prevKey' to ',' with press/release accordingly and the two 'nextKey' to '.' with press/release accordingly
