Geocouch shasum changed

[apjanke]

The SHA sum for the current geocouch file (https://github.com/couchbase/geocouch/archive/couchdb1.3.x.tar.gz) has changed some time between July 2014 and now, so attempts to install from source get a SHA mismatch error.

It changes every now and again. See #436, Homebrew/legacy-homebrew#42498, Homebrew/legacy-homebrew#49813, etc.

The problem in part is that we're not using a real tarball. It's tied to the upstream branch and every time they push a new commit to that branch or do something that tweaks the git history the checksum borks.

We could probably deal with this more obviously by using a git checkout, branch and revision, but that won't address the root problem that we're not using a "real" tag or release point.

I think this is also a problem with a redirect not being followed, too. I get the same SHA when I download other geocouch versions as a resource in a formula.

I'll just bump the SHA value once I get the redirect figured out; you're right about other options not addressing the problem.
