the full path is being passed currently in production (https://github.com/dmwm/DAS/pull/4154#discussion-diff-9946280R98, but os.path.join would be nicer), however the ```#include``` directive in cheetah, would fail as it's dumb enough trying to import files directly from the current dir, and not from templatedir.

changing dir to the templatedir just before rendering works-around this issue, and ```#include``` works fine.
