possible documentation tweaks

I would like to suggest the following enhancements :

Add a link to FD documentation in "support" section of https://www.fusiondirectory.org/
In http://documentation.fusiondirectory.org/en/documentation/admin_installation_migration_1.0.9, a quick method to backup/restore the phone entries could be suggested (ldapsearch/ldapmodify).
For the sake of clarity (that it is a conditional assertion), sentences like "Upgrade the argonaut.schema if you use the argonaut plugin" should be reversed with "if you use X, do Y" instead of "do Y if you use X". I noticed this in migration documents from 1.0.8.8 to 1.0.9.1. It's ok starting from 1.0.9.2
