[Makrennel]

This is an older version of eww, so a downgrade, and will not successfully build without a patch because of rust nightly changes - which is why I used a git commit version instead.

[Makrennel]

Actually, I can probably use an older version of rust nightly for the main package, and create a separate git package but I'm not entirely sure it's necessary to use the older release version over the git version - is there a problem with the git version?
