Subject: #1931, #1932, #1933, #1934 - movieplayer view and movie_img function
 in items model

Many changes to movieplayer view and movie_img function in items model:
- include control bar height when dimensioning movie player
- provide a default "guess" at height and width when they are set as zero in items table
- resize movie player once the video is loaded based on its actual metadata
- add get_movie_img event to provide flexibility for altering/replacing the default Flowplayer v3
