ENYO-2616: Turn Ares into full panel layout

First step to apply panel layout to Ares.

Next steps :
* When the last file is closed in code editor, we need to remove it from Ace (will be fixed by ENYO-2310) and to close code editor. The middle panel should  take the rest of the screen. Related JIRA : https://enyojs.atlassian.net/browse/ENYO-2693
* When one of opened files is closed, the parent file does not become active (will be fixed by ENYO-2310)
* Make possible to stack Ares pannels. By this way each of them can be displayed by a simple click. Related JIRA:
https://enyojs.atlassian.net/browse/ENYO-2697
* Ares project edit menus are hidden by onyx toolbars or hermesfiletree
* On FF, DND icons are displayed on a bad place
* Some issues on ace editor and right panel. Ace is not resized when RP is active.
* If one file name is longer then harmonia panel, the end of the file name is masked under the phobos/deimos panel

Tested on Windows 7, FF, Opera, IE10, IE9, Safari, Chrome, Chrome Canary
