Change style options and a new setting for intializing

[nyroDev]

• Move markerStyle to markerTip.style to be more consistent
  • This update will be a breaking change
• Move javascript inline CSS into CSS file
• Add marker.style option to be able to customize each marker on it's own
• Add directInitialize setting : this is useful if you want to initialize markers later on (ex: when depending on vtt loading)

I updated the doc as far as I can see, but some elements still need to be done:

• Update History changelog
• Regenerate all files correctly (I did it by hand for non compressed file)

Hope this will help.

All the changes look reasonable to me except moving/addition of markerStyle.

I'm inclined to not make this change since it is a big breaking change to the API. Moving markerStyle to markerTip.style isn't appropriate either because markerTip is used for the hover-over pointer thing.

@nyroDev sorry for the late reply. Just took a look and commented at the code change.

Just took another look. Currently, we offer the ability to append class to marker object like {time: 9.5, text: "this", overlayText: "1", class: "special-blue"}, which achieves the same thing as passing a style object.

Is there a scenario where you can't pass in a class name and need hardcoded style?
