Ignores jinja-style config values

fixes #26

If a config value has a jinja-style value, treat it as blank.

--secret-cfg support for CLI secrets

releases #25

• Adds render_secrets() to prosper_config module
  • uses jinja2 templating to obscure secrets
• Adds --secret-cfg switch to CLI template
• Updates get_local_config_filepath() to use os.path utilities rather than just string replace()
• Updates tests for python3.6 (python3.5 might not work any more)

sample credentials.ini file:

[logging]
    discord_webhook = https://discordapp.com/api/webhooks/99999/fake-fake_fake-fake
    slack_webhook = https://hooks.slack.com/services/T1FAKE/B1FAKE/fakefake

Flask Utils

Adds gunicorn.conf entrypoint and FlaskLauncher CLI template.

• Merges #23
• Fixes #20
• PEP updates to internal logging calls, % formatting
• Improves code smells per CodeClimate report
• Prunes deprecated code from prosper_config
• Removes prosper_utils. Moving to ProsperTestUtils
• Improves test coverage for prosper_cli
• Increments docs for new features
• PEP: adding trailing commas

Fixing PyTest issue

Adding -p no:logging to testing command. PyTest 3.3.0 added automatic logging which conflicts with logcapture.

Adding common CLI framework

Fixes #18: adds a framework so all Prosper CLI applications have shared arguments/logger/config
Fixes #17: adds custom_args to log-handle builders so special platform information can be included

Using Plumbum's framework, adds a parent wrapper to provide common args/functionality for CLI writing.

• Handles logging and configuration loading
• Reserves common arguments
  • -d/--debug: set self.debug to avoid spamming production services
  • -v/--verbose: enable logging to stdout
  • --config: load custom config
  • --dump-config: dump default config to stdout for setup

Additional Changelog:

• Removes deprecated functions get_logger & get_config
• Updates docs for prosper_cli
• Adds note to docs about prosper_version behavior

Better behavior when loaded as dependency

Fixes #15

• No longer tries to echo parent git branch when loaded as a dependency
