Change CLI arg parsing to use salt.utils.args.parse_input()
Fix unused import
PEP8
Allow for None to be passed on the CLI
No need to re-parse the data in minion.py

The args will have already been parsed before the arguments get here, so
calling salt.utils.args.parse_input here actually breaks the minion.

Also, made a slight tweak to load_args_and_kwargs().
Rename CustomLoader to SaltYamlSafeLoader

More descriptive this way.
Fix refs to CustomLoader
Make yamlify_arg use our custom YAML SafeLoader

Adds a third boolean parameter, merge, to pillar.get() for situations where the returned data (dict) should be merged with the passed default via salt.utils.dictupdate.update(). A convenience param for creating default pillar data in situations where grains.filter_by() is unnecessary because no actual grains need be filtered.
