actually merge the release/v0.2.0 branch!

My life has been a lie until this moment...
I had done:
git merge -s ours release/v0.2.0
to avoid deleting the debian folder...
but that left the src untouched...

Now I just rm'd the src folder and did a
git checkout release/v0.2.0 src/
... and merge happy! :)
