TYPO3 Core

The "all workspaces" tab currently is only available for admin users. However, there's no need to disallow regular editors to use this feature as well - access will be granted to workspaces that have been defined for each particular user or group.

Besides that, actions from the "all workspaces" view need to be handled in a special way since there is no correct BE_USER->workspace value assigned in that case and working with records require the correct workspaces scope to deal with the correct t3ver_wsid values.
