Subject: Fix: Allow negative frame id in scene.setCell (scripting). (#345)


This fix is necessary for creating animations in Javascript from raster images
with only one frame. For this Opentoonz expects a frame id of -2.
A frame id of -1 is an empty frame.
The original implementation onyl allows positive numbers.
