[TYPO3-core] RFC: #14097: Preview in BE opens Workspace-preview

[Steffen Kamper]

Hi,

change to enable the FE preview also for live now is easy if wanted. As 
it didn't worked correct before i was unsure what the wanted behaviour 
is, and i asked Peter Foerger and Jeff Segars and we all came to the 
conclusion to show ws preview only when user is in workspace.

If this isn't the wanted the behaviour following can be done:
Only change needed is in t3lib_beFunc line 2663

The condition
top.TYPO3.configuration.inWorkspace !== 0 && 
top.TYPO3.configuration.workspaceFrontendPreviewEnabled

has to be changed to
top.TYPO3.configuration.workspaceFrontendPreviewEnabled

that's all.
