Add edit project button on project detail page

[di]

Fixes #2810.

The button is only shown for logged-in project owners via a client-side include.

thanks for this @di.

One flaw in the template - if a project does not have a release.summary then the whole grey horizontal bar will not show, including the edit button.

In this case, we want the bar to show, but with the edit button alone.

Therefore the logic for the whole horizontal-section should be (excuse my pseudo code) if project.release OR edit project button.

@nlhkabu Unfortunately it's not that simple, because the edit project button come from a completely separate request. We only know whether it will be displayed or not within the edit-project-button.html template, not within the parent.

A few things we could do:

• Always show the grey bar, and show some fallback text if there is no summary instead of hiding it, like "No description provided."
  • Downside: Can't save that little bit of screen real-estate in the edge case where the project has no summary and the button isn't there
• Move the "Edit Project" button somewhere else
  • Downside: I don't know where else it could go
• Move the entire summary & grey bar into the edit-project-button.html templage
  • Downside: I'd rather keep the client-side-include as simple as possible

I think the first one makes the most sense to me, thoughts?

Thanks @di - I've updated the template to use fallback text - the first option you suggested. I've also done a quick style update to ensure this looks good / stacks well on mobile, with and without a button :)
