Allow dependent image pull from insecure registry

PR #490 Provides the ability to pull from an insecure registry by passing --allow-insecure-ssl. This commit extends the work done in #490 and adds the ability to pass --allow-insecure-ssl to the `up` and `run` commands which will attempt to pull dependent images if they do not exist.
