Install duplicity with custom backend

Btw. I compiled the 0.7.06 version (manually), downloaded https://raw.githubusercontent.com/havardgulldahl/jottalib/master/src/duplicity-backend.py into ````duplicity/backends```` renamed it to ````jottabackend.py```` and installed duplicity using ````sudo python setup.py install```` Now I use a duply profile with a pre and post script to set the Environment (````export JOTTACLOUD_USERNAME="username" + JOTTACLOUD_PASSWORD="password"````)

You then have to use ````sudo -E duply ...```` to keep the environment variables.
