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

README is now present in $(datadir)/doc/lodel2/
And as README.gz in /usr/share/doc/lodel2/ for debian packages

with make deb . Next commit will update the README

Now mass_deploy is able to stop when slim fails indicating on wich action slim fails
Bufixing webui conf edition

Before when session restore fails the webui was answering "Unknown status 200" as content.
Now it produce 2 log messages (maybe)

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)

using --plugin option instead of uwsgi_python3 shortcut (can be uwsgi_python34 etc)

Now we can run tests from the tarball generated by make dist

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