IMPORTANT : tests are broken. See details below

A new lodel/buildconf.py.ini file created. It will be transformed to a lodel/buildconf.py file by ./configure .
This file goal is to store build time constant (for the moment the presence of pymongo).
You have to build lodel2 before being able to run the tests.

Created groups (they can be found under the "Modules" menu -_- )
Created new pages : on LeAPI EditorialModel Plugins etc

- DatasourcePlugin implmentation as child class of lodel.plugin.plugins.Plugin
- moved methods about datasource initialisation from LeObject to DatasourcePlugin ( _init_datasource(), plugin_name(), _get_ds_connection_conf() ...)

Deleted hardcoded condition that brokes standart field validation process

Now lefactory inject python code from lodel/leapi/lefactory_common.py in generated code

- webui now calls a hook to indicate a session end
- loader.py now set a lodel.dyncode module exposing dynmically generated code
