[#1363] Code style & transitions keyframes

Renamed getKeyframePositions to getTimelineObjectPositions
Moved more logic inside getTimelineObjectPositions
getTimelineObjectPositions now only takes the object as argument (eg. selected_clip or selected_trans)
Added functionnality for transitions as well as clips
