[TYPO3-dev] Moving Workspace code into a separate system extension

[Benjamin Mack]

Hey Ingo,

we also discussed with some others that everything that belongs to 
workspaces and is in the topmenu should go in a topmenu-dropdown (like 
the others) to make it consistent with the other topmenu-dropdowns (search).

====
In there should be:
  * Workspace selector (maybe radiobuttons?)
  * Checkbox "Frontend preview"
  * Link to Workspace Module

Also, the workspace icon in the topmenu should differ if you're in Live 
or other workspace.

Makes sense?
