[FIX] web_diagram, unlink connectors/transitions between nodes from the diagram view (transitions IDs sent to the web client were strings instead of integers)
[FIX] product: pricelist, uom and price_surcharge

The price_surcharge attribute must be computed based on the reference unit of measure (divided by the factor).
This is to make sure than 12 units and 1 dozen have the same price after pricelist computation (opw 599727).

Added test checking the correctness of pricelist computation based on unit of measures.
[FIX] product_visible_discount: discount with different unit of measures

The computation of the price without pricelist should take care of the unit of measure.
e.g. if computing discount for objects in dozen (on a product with price in unit), returned unit price should be (price*12) where 12 is the factor to go from dozen to unit.
Otherwise the compared prices (with and without pricelist) would not use the same unit of measure and the comparaison would be inconsistent. (opw 599727)

[FIX] product_visible_discount: use on_change result for product value

At the end of the onchange call product_id_change, the uom may have changed (e.g. if product in different category).
To compute the quantity, we need to use the new uom and not the first one (that may be Unit, default value)
[FIX] Fix for Issue 2716: Hide 'Print' button for the report 'Timesheet Profit'

The report 'Profit Timesheet' shouldn't be directly displayed in the views related to the model 'account.analytic.line' but only from the reporting menu. In facts the report requires a popup to specify the report parameters.

[IMP] fields: reduce the number of attributes on _column instances

This is a memory optimization: instead of setting all attributes on all
instances, set them with their default value on the class, and only set
specific ones on instances.  This reduces the memory footprint of around 14Mb
per registry with modules crm, sale, purchase and stock installed.
[FIX] stock: forbid adding new lines when processing picking

Source and destination locations are required and not displayed in the form view.
Adding new items when recieving a picking can not be easily guessed as we can put different locations for each line, using default locations may not be the expected result.
Instead should modify the original picking or create new one.

[FIX] account: fiscal position may map single tax to multiple taxes

(This is a regression in Odoo 8)

It should now work when a fiscal position replaces 1 tax with
several taxes (for example : Fiscal position "Intra-EU B2B" in l10n_fr)

[FIX] Regression in image resize helper (Fixes #2529)

Commit 57ad514b makes the function preserve the aspect ration of the
original picture. Error of mine because the expected behavior was to
lose it for kanban view purpose.

For backward compatibility sake, this commit will keep the old behavior
by default.
[FIX] sale_margin: cost price uom

When computing the cost price to display, take the uom into account. The cost of 1 Unit or 1 dozen should not be the same. opw 599727
[FIX] fields: inherited fields should get 'string' from their parent field

Because some parameters of a field may be determined during its setup, we have
to update the corresponding column after the setup, and recompute _all_columns
to make it consistent.
