Just merged ynh5 of the #flohmarkt #yunohost app. Soon it will be available on the yunohost catalog.

• multiple installs of flohmarkt on the same yunohost should work
• backup, restore and remove now only affect the CouchDB database and user of the actual instance of flohmarkt (thanks to Daniele Bailo for couchdb-dump)
• symlinks are generated to distinguish between the flohmarkt, flohmarkt__2, flohmarkt__x directories when having multiple instances installed.
