Corrected API method name

Corrected API method name and added helpful message on using events.

I was confused for a while regarding how to use the events, so it might help someone else.

Corrected API method name (#1330)
Updated stable with new contrib commands, including test, watch, server
The base media tech class now checks the networkState at init to determine if loadstart should be manually fired.

Previously this was only done in the HTML5 tech, but Flash needs it as well. This relies on videojs/video-js-swf#106.

Also removed the 'not implemented' warnings from the media tech functions. I think there's a better way we can help tech authors here, and it was blocking the ability to check if a function was implemented for real.

Fixes #1300, fixes #1341
Updated to swf version 4.4.2 to fix the network state reporting
Updated contrib release steps
Release 4.6.4
