Homepage - adjust branding

[stufraser1]

Scope of this geonode narrowed - homepage to be adjusted accordingly

• [ ] To be branded as ThinkHazard Geonode - use TH! logo, rather than innovation labs logo on homepage
• [ ] Image to match logo style
• [ ] Add text to describe scope: as support to TH! - GFDRR to provide
• [x] Remove Vivien email for feedback, replace with link to TH! feedback form
• [ ] Add footer with three logos, to match riskopendata.org

To be branded as ThinkHazard Geonode

Think Hazard! logo in geonode:

@stufraser1 is it what you want ?

Image to match logo style

Do you want to change "Hazard datasets" part with a black background and logo in white ?

[stufraser1]

Looks good but please put on hold for now - pending discussions on branding of other Labs tools
