Title: Use a forked version of lettuce that fixes a bug with tag inheritence

Lettuce had a bug in which tags applied to a Feature were not inherited by all scenarios. They were inherited only by (a) the first scenario and (b) scenarios that already had tags.

I forked the repo, fixed the bug, and have updated our requirements to point to the fork. This ensures that sharding by tag will work correctly.
