Merge branch 'show-invalid-projects-google-code-import' into 'master'

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.

Closes #1531
