This is a simple renaming without adaptation.

The style of a primary/link button is given by the
'btn-primary'/'btn-link' class. The old 'oe_highlight'/'oe_link'
class should still be supported in views but not rendered in the DOM.

Issue: when displaying the shortcuts with ALT key, when a dialog is open
the shortcuts are displayed in absolute position above the gray overlay
of the dialog, so it is possible to click on the buttons of the
shortcuts.
This fix will remove this possibility.

This commits aims at adding an accesskey (a shortcut) to all buttons
in odoo. This is done by either by assigning an accesskey in the view
XML or by automatically assigning a key to the buttons using the first
available (not yet assigned as a shortcut key) letter of the text of the
button, failing that we use the latin alphabetical order to find the
first unused key.

Included in this commit:
    1. Using the ALT key, automatically assign
    2. When the ALT key is pressed, show the assigned shortcuts
    3. Assign a number to the menu items (enterprise)
    4. Activate number accesskeys without using SHIFT
    5. Extra logic to support the activation of the alphabetical
        accesskeys without needing to add the SHIFT key in the key
        combination (except for Firefox on linux)
    6. Assign a fixed accesskey to the search field

Not done:
    1. Executing the primary action on dialogs using SHIFT+ENTER
    2. Show the input using TAB on the appswitcher screen

Things to consider:
    1. Fixing more access keys on forms that share the same features
        (b.e. Validate in customer invoice and vendor bills)
    2. Not assigning keys to the chatter section

Before this commit, the boolean_toggle widget was rendered
but the less contained errors that prevented it from displaying correctly
This was due to commit 9dead7e3d33ee0ddafb55060b3f95027e9330e55

After this commit, the widget displays correctly

There might be an issue in the future because of
field_utils.formatBoolean, when this function decides to pass the full options dict

- bg-*-full color classes were only defined in enterprise while they
  should have been defined here (fixes kanban column progressbars)
- new @gray-lighter variations should be defined in variables.less
  as they are bootstrap extensions, not bootstrap overrides

- Review UI custom colors (used for tags and kanban cards)

- Properly align control panel items

- Remove links style overrides (these rules are not necessary anymore
  because already specified in bootstrap_overridden.less variables
  definitions)

- Set new webclient bg color

- Adapt colors in kanban view
