[Libreoffice] Bundled fonts

[Sebastian Spaeth]

> 	Sounds good to me; go for it ! :-)

OK to push this patch? USer visible changes are:

Rename --with-fonts to --enable-fonts and --enable-extra-font to
--enable-extra-fonts to make them consistent. Improve help texts.
Make it so that --enable-extra-fonts implies --enable-fonts.

Both options are turned off by default, distros that want fonts
bundled need to set that in their distro conf.


Optinions? opens___.ttf will still be bundled in any case
