Add Rotation to infodisplay

[kierio04]

• Function(s) to convert quaternion to Euler angles in common.py
• Function to read in-game facing rotation as Euler angles in mkw_utils.py
• Function to read speed vector as Euler angle for moving yaw in mkw_utils.py
• Function to read previous frame's facing rotation and calculate "rotation speeds" in mkw_utils.py (may require @event.on_frame_advance and a check for increase in frame count to be able to store previous frame's info)
• Config and text addition for facing pitch/yaw/roll and moving yaw in _draw_info_display.py
• Config and text addition for pitch/yaw/roll speeds in _draw_info_display.py
