[Libreoffice] [REVIEW] templates and icons, small fixes

[KAMI911 KAMI911]

Hi Developers,

I pushed two patches to master. If you agree please cherry-pick into 3-4 too.

First one is related to templates and common (language independent)
folder is introduced
move default language independent layout templates - master

http://cgit.freedesktop.org/libreoffice/libs-core/commit/?id=faef37dc2c41b9183b91ceb06a72c6f11cc6dd65

Another one is a patch to always use libreoffice(version) as icon
name. This will solve some problem of mine with packaged desktop files
that dont have icons because of bad icon name.

Using "$(ICONPREFIX.libreoffice)-" as icon prefix - master
