Adds new field formatter (thumbnail video player). Adds field settings for setting the width/height of the standard/thumbnail video player.

make _brightcove_initialize() public by convention - now brightcove_initialize() with old function as a wrappper

Issue #1143832 by skwashd, remove undefined (and unused) $reset which was in code copied from brightcove_mapi_path()

Temporary fix of #1090426 (turn off checking of video status until the getStatus() method will be accessible for users without write api key)
