Fixed Orly test#A -> this error is a print left in code!
Idempotent `register_workflow` method, and get_or_create account

Needed because in tests, the syncdb seems to be done twice
(so we have two post_syncdb)

My fault has been done in merging :( Merged worklow work along with
simple_accounting work.

Rebase would not work
Documentation to integrate new features for accounting improvements
Dawn indentation fot InterGAS form Metaclass
Redo home pagine
Added gas templatetags
Copy meta fieldset for open orders form.

Fixes: Caught KeyError while rendering: "Key 'intergas' not found in Form"
Updated InterGAS translation
Trivial improvement on html des_notification
Merge remote-tracking branch 'origin/matteo-dev'

Conflicts:
	gasistafelice/gas/tests.py
Updated checkout for django-simple-accounting
Minor fix s/su_passwd/su_PASSWORD in doc-dev
Updated gasistafelice.exceptions to gf_exception

Fixed from previous commits
GASMemberOrder code Refactoring: tot_price --> price_expected

By passing params as non keyword arguments, the following exception was given:

TypeError: get_param_roles() takes exactly 2 arguments (x given)

Completed first phase of the order and intergas tests.
