[IMP] web: auto-assign and show access keys on ALT

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
