Fixed Motherless ripper

[brantspar]

The Motherless ripper was broken as the rip operation was not waiting on all the threads created to download the files from motherless.

This repo reminded me as to why OO inheritance is just plain bad... too hard to follow what's happening!

Also

• increased default http retries to 3 (why only 1?)
• fixed deprecation message for Motherless ripper

I have fixed the tests however the build ends with this error

Could not create new tag "refs/tags/latest-194-merge" (Resource not accessible by integration) therefore updating existing tag "tags/latest-194-merge"
  Error: Resource not accessible by integration
