Updated connect Dependency / Browserify Compatibility

[mjhasbach]

This PR makes rem Browserify-compatible. The old version of connect you were using exported like this:

module.exports = process.env.CONNECT_COV
  ? require('./lib-cov/connect')
  : require('./lib/connect');

./lib-cov/connect was a non-existent module, which caused Browserify errors.

I reviewed the rem source code, and adding the cookieParser and cookieSession middleware seemed to be the only things needed to make rem compatible with connect 3.3.4. I ran tests/oauth-restore.js and it worked.
