Some additional fixes after Jinja2 integration
Cleanup: source is never None
Cleanup: Get rid of two simple functions

Import cleanup: Explicitly import stuff

Also remove unused import. Previously it was hard to notice that it
was no longer necessary. This is why explicit is better than implicit.
Minor cleanups: Remove unnecessary assignments
Cleanup: Unwrap parameters
Cleanup: Remove some unnecessary blank lines
More imports cleanups
Minor changes to ease further changes
Update projects.json
Fix deployment script
We need Polib 1.0.4 to process successfully some of the Grimps po file
