Candidate maintenance only partly implemented

[edsko]

The package page for a candidate currently shows two "maintain" links -- one at the top [maintain] and one at the bottom in the "Maintainers Corner". The latter refers to a non-existent URL (actually, the URL is wrong, missing /candidate); the former gives a page that says

Here, you can delete a candidate, publish it, upload a new one, and edit the maintainer group.

except that you cannot in fact do anything on that page (there are no links at all).

• Publishing a candidate is partly implemented (but see Publishing a candidate does not transfer already-built docs #70 and Publishing a candidate does not delete the candidate #71) through http://example.com/package/package-name-X.Y.Z/candidate/publish (GET shows the "Publish" form, POST actually does the publishing) so that should be easy to add;
• Deleting is also implemented but only through a HTTP DELETE request of http://example.com/package/package-name-X.Y.Z/candidate so that requires a little more work to make that available through the web interface.
• For uploading obviously we can use the existing candidate upload form
• For editing the maintainer group etc., we should probably make sure that the "Maintainer's Corner" works just like it does for regular packages.

This is from the XHtml-generating function serveCandidateMaintain in Html.hs. Should this be ripped out, and a template used instead?

I'll look at this. For deleting packages, I guess we want to create a page at http://example.com/package/package-name-X.Y.Z/candidate/delete that shows a form on GET and deletes on POST?

See #115. Sorry for the noise, I thought I'd get away with that rebase!
