[Libreoffice] [PATCH] Possibly unused OTempFileService class

Hi,

It seems like OTempFileService, defined and implemented in
libs-gui/unotools/source/ucbhelper is unused.

There's no mention of this name elsewhere in the tree, and LibreOffice
builds and run fine without the files removed by the attached patch.
One of the methods of this class is already in the list of unused functions.

Howewer, since it involves UNO, this code may be loaded at runtime by an
obscure corner of the gui I'm not aware of.
Could someone confirm if it can be safely removed (or not) ?
