fix the 'wrong keysize' error

closes #59
include README.rst (required by setup.py) in manifest
Merge pull request #56 from justquick/master

Add the missing README.rst to MANIFEST.in

(it seems like generated tarballs/zipballs already included README.rst,
perhaps due to some other fix landed since this branch was created, but
it's a good idea to include it in MANIFEST.in anyways)
