[IMP] Packaging: Debian, RedHat: No more superuser for odoo role

only create db
[FIX] website_instantclick: this lib create some bug because the odoo assets are loaded in the body and some event are binded more of one time. Change the js lib  because the xml can't be change in 8.0. TODO: move assets into the head and fix js files and remove this commit in master
[FIX] mail: access link generaTION

Catch only the error related to the access of the linked record.
Previous was hidding error to access the ir.config_parameter and eventual other
errors from the orm.
Uses SUPERUSER_ID to access instance URL (e.g. portal has no access to it).
Fixes #4234 #4234
[IMP] module/loading: do not try to load module graph when nothing to load

This simple optimization in load_marked_modules() avoids unnecessary calls to
load_module_graph().  This provides a small speedup, and avoids confusing log:
some module updates were making it look like the registry was loaded 5 times
instead of once.
[ADD] doc: setup documentation

* Odoo installation from packages or source
* Deployment instructions for production environments
* dbfilter

Add missing support for disabling xmlrpc(/http), useful for WSGI
deployments which require running cron-only Odoo instances.
[FIX] update README about the new documentation
[FIX] odoo.py setup use 8.0 instead of master
[FIX] product: find products of subcategories

When searching products for a specific category, display the products of the whole category subtree.
[FIX]web_gantt: value rendering with decimal separator other than dot
[MERGE] forward port of branch 7.0 up to 60a361c
[FIX] website_mail: avoid error when message.body is empty
[FIX] web_gantt: duration in business days if delay not set

[MERGE] forward port of branch 7.0 up to f833d2e
[FIX] point_of_sale: account selection for payments

Registered payment uses the partner receivable account. As this field is
a property field, it will select different accounts based on the user that
registers the payment (in multicompany).
Should use the company of selected journal instead of the one of the user.
[FIX] payment_buckaroo: dynamic lang & test params

test flag is set according to acquirer environment
lang is set according to partner language
[FIX] payment_buckaroo: api expects iso culture as language param

IT looks like this is the code we use in partner lang, by replacing the '_' (underscore) by '-' (dash)
[FIX] purchase: supplier invoice and purchase order count

Value of purchase_order_count and supplier_invoice_count should be coherant with
the behaviour of the button on partner form: count records for the contact of
the company as well.
Fixes #4224
Reintroduce fname kwarg in configmanager

In [f04f409], the configmanager's __init__ lost its fname kwarg, which
allows to pass the name of the config file to read (or write).
Without it the only way to programmatically specify this file name is to
use the OPENERP_SERVER environment variable, which may be unpractical and/or
subject to renaming.

External tools (such as the buildout recipe) may need to pass this file in a
clean way.
[FIX] web: autocomplete selection not hidden

Appending the autocomplete selection too close from the input field leads to display (hidden) problem in some cases (Many2one inside modals views, many2one at the end of a form view, etc.)

This is related to rev. e1cde4d0383124c0636c518185f2222055afa3b5
