Content plugin in Tinymce editor

[ch2856]

1. There should be an option to have all content plugin buttons in the editor toolbars and not under "CMC Content" dropdown.

2. Media in article editor. When a user upload a single image to media, that image should be automatically selected so no need to search for it and it's easier and faster way to add an image to an article (Drag and drop is not always comfortable to use) . Alternative to that, just to have a button to allow sort by date.

3. For people who use D&D, there should be an option to add caption right through the popup next to the Alt field. else you need 3 steps to add a caption (Figure Caption).
