mass_deploy now warns you when using $RANDOM instead of pwgen or /usr/share/dict/words

with make deb . Next commit will update the README

Bufixing webui conf edition

broken nginx conf + absolute path in slim that is known only at build time

Remove duplicate install templates directories (the same directories can be used by SLIM & runtest)
Addapted runtest so it can fetch the install template from the lodel2 datadir
Make lodel_admin.py runnable (add the python3 shebang + chmod +x at install-data target)
And a beautifull ASCII formating for the README

Allow to remove all database prefixed by MONGODB_DB_PREFIX (in the conf of mass_deploy script)

Allow generating a tarball that can compile and run lodel2 + deletion of unwanted Makefile.in files

Forgotten file was the PID list file
The bugfix concerns the conf when selection mongodb as datasource (quick & dirty solution : keep dummmy_datasource loaded so we don't have to modify the original datasource conf)

Bufixes in start & stop functions
Add a -f --foreground option allowing to run an instance in foreground
There is one problem left : the unix socket creation is not done in the instance directory...

Bugfixe in start
implements stop
add info in instance details
