Subject: [PATCH] Switch to yaml.safe_load(_all) to prevent YAMLLoadWarning
 (#1688)

* Switch to yaml.safe_load(_all) to prevent YAMLLoadWarning

* Change all usages of yaml.load to yaml.safe_load

* Extend PyYAML's SafeLoader and use it with `yaml.load`

Also added convenience functions for using this loader for reuse in
`roslaunch`

* fix typo in rosparam.yaml_load_all

* Modify Loader and SafeLoader in yaml module directly

* Revert whitespace change

* Revert unrelated change to import through global variable construction
