Plugin Doc and Example
Added most of a doc on building plugins. Still missing a section on up-front plugins. Created an example page that shows how to load a plugin.
Remove Extra Flash Switch
Get rid of the extra switching logic to force Flash tech. Worth noting: it has to exist as a separate script tag because we're using document.write to insert video.js scripts.
Up-Front Plugin Config
Create an example of making a dynamic video element and loading a plugin. Add that example to the tutorial.
Remove Up-Front Config Example
Get rid of the example code for configuring a plugin at creation time. There's already an example in the tutorial and it makes things a bit confusing.
