[Libreoffice] [PATCH]: Remove large blocks of unused code + script to find large comment blocks

Removal of two more large blocks of unused code.

For anyone interested in searching for more, I have attached a script
that prints out the line size of the greatest code block in every file
below a supplied directory. It is quick and dirty and certainly not
bullet-proof, but gives a hint of which files are worth looking into.
