Relative symlinks in xfce docs

[Andreas Mueller]

Hi

I know the world is not going down without but for me - implementing xfce 
support in Openembedded - it would make life a bit easier and others won't feel 
the difference:

https://bugzilla.xfce.org/show_bug.cgi?id=7816
https://bugzilla.xfce.org/show_bug.cgi?id=7828
https://bugzilla.xfce.org/show_bug.cgi?id=7829

A similar patch was already included in exo ( see 
https://bugzilla.xfce.org/show_bug.cgi?id=7379 )
