* database: Fixes 51 - Give the user an error when the database file does not exist (in connect_db function). Except for the case of the initialize function.
* query: The query command now supports querying for wildcard only actions at an access level per service. For example, the only wildcard-only action under S3 at the Permissions management access level is s3:PutAccountPublicAccessBlock
* query: The query command now supports yaml output. This Fixes 95 (output in the Query command) but does not fix 11 (since 11 is asking for the write-policy command to support YAML, and was before the query functionality came out).
* query: the get_actions_matching_condition_key_crud_and_arn is available. This provides some scaffolding for 21
* travis: Auto-deployment of Python package with TravisCI
