[IMP] procurement_jit: check availability of products directly
[IMP] assign moves to existing picking, even if reserved, but not if printed
[FIX] increase SO quantities: new procurements created
[FIX] typo in res.config.py

Tag template data were wrong since many2manytag color introduction

And why the hell are these many2many fields called tax_id and taxes_id

the product is not stockable

CSS to LESS
Adaptation to new webclient

* Missing oe_title
* Wrong indentation

Since it is possible to select several SO and generate the invoices at
once, it must be possible to view all these generated invoices.

Due to new Sale module

It allows people to only use the rating service of the sales orders

QWeb's LazyResponse mechanism allows controllers to be inherited
and to alter the rendering context (qwebcontext) *after* calling
super().

However it caused the final rendering to occur outside the protection
of the @service.model.check decorator that handles concurrent access
errors. In rare cases the lazy rendering can be interrupted by
a concurrent access error, for example when bootstrapping the
the cache of asset bundles (as it INSERTs a bunch of attachments).

By forcing the flatten()ing of the lazy response earlier, right
after calling the route's endpoint(), it occurs within the
protection of the @service.model.check, and benefits from the
automatic retry.

flatten() was modified to avoid rendering twice the template
The flatten() in get_response() is still necessary for addons
code that directly calls get_response().

Moved QWebException into openerp.exceptions next to the other
exceptions classes - since it now has more global semantics.

The whole request dispatching code could really do with a
complete redesign/simplification.
