Editing v2, Menu, Color theme, Flyout menu

* Drag'n'drop of toolbox rows can now happen in all containers (header,
sidebar, footer...) instead of "just" the main container
* Swapping of page elelements can now happen between all containers
(header, sidebar, footer...) instead of just the main container
* Clicking on a menu item that has no submenu item redirects to that
url, clicking on a menu items that has a submenu does not redirect IF
the device is a touch device (this enables sub menu's to show up)
* Colors are now identified by a name (for example "Tier"), not by its
pair (for example "Tier1", "Tier2"). The pair is automatically derived
by the color (so "Tier1" and "Tier2" still exist).
* Framrwork defaults colors to "tier" and "base".
* Fly out menu now draws color pairs underneath one another within the
same box since the pairs are linked.
