[Libreoffice] XDG config migration

[Tomáš Chvátal]

Hi guys,

After updating to 3.5 quite few people reported that their
configuration is gone and they have default setup.

The reason for this is that 3.5 now uses XDG spec
~/.config/libreoffice instead of ~/.libreoffice. Simple copy of later
folder to replace the former one solved the issued for everyone.

In my humble opinion I think that this migration should be done
automatically and user should not be bothered by this (even packagers
should not do this as we should mostly NOT touch user homedirs).

Cheers

Tom
