The onboarding modal for setting up the few base fields of a company
has now been moved to a wizard
It is accessible from the general settings, but also in the onboarding
section of sale and account modules.

The following company settings are editable with that wizard:

- Set report layout:
    The user can chose the overall look of the report. The current choices
    are : "Standard" (default), "Background", "Boxed" and "Clean".
    Each layout has its own pair of default colors.

- Set company logo:
    Changes the company logo.

- Set report colors:
    The user can set the primary and secondary colors of the report through
    a newly added widget allowing to pick a custom color.
    Colors are automatically changed when:
    > changing company logo:c olors are computed from the logo
    > changing the report layout:
        colors are set to the default colors of the new layout
    A "Reset colors" button is shown when using custom colors, allowing
    the user to set the colors to the layout default colors

- Set report font:
    Changes the overall font of the report. Only Google Fonts are used
    for enhanced compatibility.

- Company tagline, also called "header"
- Footer
- Paper format
- Report preview:
    A mockup of a final report
    Reacts to changes of relevant fields
