Mongo sux ?

solves #185
typo fixing

added a default value for Subsection parent field

adds a default value to Publication collection field

Previous bugfix on runtest & create instance brokes deployment, now both seems to work fine

concerning unittest & field validators

Fixes problems with plugins

- updated scripts etc
- make tests pass

- Replaced some "hidden" import with LodelContext.expose_modules calls
 - in some functions of Setting, Plugin, validator
 - in loader.py (temporary version)

In this state the tests runs (151 success), I'm able to run an instance (from debian package using slim) in MONOSITE mode and in MULTISITE mode by creating and loading a context in the loader.

Add master = true to uwsgi.ini

Add the possibility to give a fixed name to instances created by mass_deploy

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

Now mass_deploy is able to stop when slim fails indicating on wich action slim fails
