Fix empty logo.png file

Note that there is a SVG image in the repository, however it it not currently a square image. It could be a good novice issue to take the SVG image and produce a PNG logo compliant with the Project Browser requirements.

Not really, the SVG logo is the one of the company who created the module. It has nothing to do with the module functionality itself :-)

Thanks for calling this out, we are working on an updated logo for Prototype. Till that is completed this will be marked as postponed.

Assign to philip_stier to take a first pass before stable release.

@jldust - Logos refreshed and I've also added a favicon style logo for the page :)

The proposed logo in #6 does not meet the requirements for Project Browser:

- Create a logo that is 512x512 square dimension in PNG format without animations. Suggested file size should be 10k or less. Note: Please do not round the corners of the PNG itself unless there is some compelling branding reason. Corners are rounded automatically when displayed in the Project Browser.
- Use a lossy image tool (such as pngquant tool or the tinypng.com online service) to reduce file size while keeping the image quality at around 80%.
- Place the logo in the root directory of the Git repository for your project, on the default branch. The logo file should be named logo.png. The logo will appear on Drupal.org project pages, to the left of the project name. Logos are cached and may take up to an hour to show.

Thank you for the direction @leslieg!

@jldust - I've created a merge request that replaces the current logo.png file (corrupted) with a new one featuring the new branding. I even re-introduced the blue that you were missing so much >_<

Thanks for all your work on this, we have merged the new logo in and it will be included in the next tagged release.
