As an editor I want to access additional information about the tool.

Problem:
We need to link to source code for contributions and phabricator for bug reports, potentially others. We should also indicate that it is a tool developed with <3 by WMDE. This could happen in a header or footer.

Example:

• https://interaction-timeline.toolforge.org/
• https://query-builder-test.toolforge.org/

Screenshots/mockups:
