browse_links and other popups don't work, when in Admin Panel "Editforms on-page" is checked
If you use Frontend Editing and you check "Editforms on-page:" in the Admin Panel you won't be able to use several modules like the browse_links, acronym, user elements.
$TSFE is not there, when using the popup for editing, but it is there, when editing inside the page with the above mentioned option.
In the patch I removed that condition, but as it was added in 4.1 and I don't know the reason for that, there might be some problems again at other places, that I didn't realise...
