Native Mp4, Webm, Ogv video support.

Implemented native support for mp4, webm and ogv video files. 

Tries to detect if the browser supports the video format using `canPlayType` function. The function will return the strings `probably`, `maybe` or ` `. It will add the inline video player if the function returns `probably` or `maybe`. You can never be sure if the browser fully supports the video format until it plays. But this should cover 99%.

Browsers tested:

* Google Chrome 35.0.1916.153 m
* Opera 22.0.1471.70
* Firefox 30.0

Hrm, I've been wanting to ditch the maxWidth and maxHeight stuff in this module for a while in favor of a "fit to screen" feature... I think that'd be a better solution than a hard width of 600px... that or at least for now we use the user's set dimension that we have today?

Also I haven't pulled/tested your PR, but does drag to resize work?
