Added new shot to Shot Explorer, shot called Area Shot. Area shot take into account all characters near the focused one and extends shot so that the characters are all in the shot;
Fixed Left to Right shot rule so it takes the proper center of the shot;
Fixed Establishing shot zooms in when the camera angle is lower than ground;
Adds support for character models with similar to built-in character skeleton
