v1.1.1

Improvements

• Stemcells are now pinned to 3468.latest, instead of latest,
  since that is the major version that our compiled BOSH releases
  are compiled against.

• When deploying to vSphere, genesis new now asks for what
  resource pool you want to deploy to, underneath the cluster,
  and generates the appropriate environment YAML structures.

Bug Fixes

• Fix bad default value for params.trusted_certs (should have
  been an empty string instead of nil. Now it's an empty string,
  and all is right with the world).

• The aws_key_name being erroneously emitted by genesis new
  for the AWS IaaS/cloud is no more, leading to less confusion
  when deploying to Amazon EC2.
