New Extension Icon

[pento]

The extension currently just uses a generic icon, it should be replaced with something project-specific.

Some things to consider:

• While this project is associated with WordPress, it doesn't necessarily need to use WordPress branding up front. The focus is on "escaping CMS lock-in", rather than "coming to WordPress".
• It'd be useful if it worked in multiple states:
  • disabled (the extension doesn't export anything on the current site)
  • not ready (the extension supports the current site, but needs additional information before exporting)
  • ready (exporting can begin)
  • in progress (we're currently extracting the export)
  • error (something went wrong whilst exporting)
