Fixed Bug #1511: Cannot access files in default folders.
The URL for a file-storage folder contains I18Nized strings and the
tcl pages don't localize them. Furthermore some of the links were
missing @?version_id=@contents.live_revision@
Files in default folders can now be accessed, but there is at least
one more I18N glitch.
(Also file-storage is over-agressively noquoted)
