FitVids.js is not compatible with the JW Player 6 because it breaks the way the player
is embedded in the page. If you enable fitVids, the player will briefly show and
disappear immediately after. Patching fitVids would be the best solution, but because
fitVids is included with so many themes and plugins, it would take a lot of time
before all of them were updated too. As a solution, this plugin disables the fitVids,
by redeclaring the function before a player embed. If you want to disable that because
you've update the fitVids lib yourself, you can change the setting below to false.
