Add 1.5.7 dist tarball

Addresses issue #30

Currently, moto does not install correctly due to unpinned requirement on dicttoxml. Pypi download link to the 1.5.7 tarball is currently busted.

Adding a tarball to a git repo isn't a very good idea.

If you are looking for a place to upload the tarball, pypi seems like a much better place and it's quite easy to do using python setup.py sdist upload

Agreed! I'm looking for an expedient way to fix the references published to pypi for this project. The 1.5.7 tarball is already published on pypi, but the download URL points to the dist/ folder in this github project.

I've changed this pull request to modify the download_url in setup.py instead, but someone with rights will have to publish that change to pypi.

👍 for that change :-)

Agreed - thank you for pointing out this issue and providing a fix that addreses it!

I've updated the README and incremented the version to 1.5.8 and pushed it to pypi.
