Show incompatible projects in Google Code import status

Using Google Code import with a JSON file that contained only one Subversion project led to confusion over whether the system was working. Display the list of valid projects if there are any, and show a list of incompatible projects. Provide tips on how to retain issue data after conversion.

@DouweM, can you review?

I think for sake of consistency, it would look better to have just one table, with a red status of "Incompatible" for these incompatible repos.

Below the table, we could then have a sentence like this:

One or more of your Google Code projects cannot be imported into GitLab directly because they use Subversion or Mercurial for version control, rather than Git. Please convert them to Git on Google Code, and go through the import flow again.
