In 0.15 accessing werkzeug.urls functions directly through werkzeug
is deprecated, the shortcut will be removed in the eventual werkzeug
1.0.

Fix existing uses of these shortcuts. Also cleanup some imports when
they're not far from a werkzeug* import being altered.

It seems that Google Spreadsheet only recognizes `true` and `false` as
valid boolean values.

This commit adapts the business code to changes introduced by
the parent commit in order to keep the same behaviour as before.

All readonly=False fields will have to be checked afterwards to confirm
that the business case requires write access to the source field.

Many error messages are misleading or too "vague"
This task aims to improve all error message.

Task #47042
PR #23321

This commit introduces a new way to hide a column in a x2m list view.
The attribute 'tree_invisible' can be add in the field attrs in the x2m
view definition. This attribute can use the 'parent' key to make a reference
to the parent record (e.g. 'parent.id').

Now that we only have one model (res.config.settings). Uniformize everything according to the guidelines.

Purpose
=======

Settings are often way too long and hard to scan and sometimes you don't know where to find the settings you're looking for.
By adding a left navigation, you can already have an overview of the settings, and switch easily between them.

Specification
=============

- Add a search bar on all the apps that have settings which can search results from all the installed apps.
  (If i'm on sales settings,and I search anything then it shows results from sales settings and also shows
  all the other matching results from all the other apps such as, Inventory...etc) with app name.
- Able to activate feature from the current page results (no matter if the searched result is from another apps).
- Highlight searched word in results
- Delete the sheet, have a full white background
- Add left navigation bar on setting
- Left navigation bar fixed
- List displayed based on installed apps
- On right panel, by default display current app setting and change accordingly
- [Mobile] Left navigation bar displayed on top
- Add Breadcrumb on top of the page: have the name "Settings" + Save / discard CTA + Search
- Add General Settings on the nav bar
- remove "save this page..." notif in all settings
- Delete all recommanded apps section + all checkbox that install app should disappear:

cgi.escape is unsafe (quote=False by default) and deprecated in Python
3. We already have an openerp.tools.misc.html_escape version which
forwards to the (modern and safe) werkzeug.utils.escape, just use that
everywhere, and convert extant uses of werkzeug.utils.escape to
utils.html_escape as well so that we do the same thing everywhere.

In Python 3, all of these were "consolidated" under urllib(.request,
.parse, .errors) which is inconvenient.

Since we already have hard dependencies on requests and
werkzeug(.urls, which is a backport of Python 3's unicode-aware
urllib.parse) migrate *everything* to that.

A sticking point is urllib2.URLError, those were (mostly) replaced by
the slightly more general IOError which URLError extends.
