Resolved the logo issue.

For some unknown reason, font-mfizz was showing the slonik icon in
italic. Even after upgrading it to the latest version of font-mfizz, the
problem was not resolved.

So - instead of using the vector font, using the PostgreSQL SVG logo as
the application icon, and documentation link on dashboard now.
