Visuals, graphics, colour scheme, branding and "look and feel" of RSQKit

[anenadic]

At some point, we'd need to start thinking about the "look and feel" of the website - colour scheme, icons and grpahics.

There are EVERSE icons at: https://github.com/EVERSE-ResearchSoftware/EVERSE-ResearchSoftware.github.io/tree/main/static and there wil probably some branding guidelines to adhere to at some point in the future.

Just creating this issue to keep track of things and remind us to revisit the "look and feel" issue.
