Add "apt_dependencies" config option for custom dependencies
Add 'requirements_path' config option for install a WSGI app's pip requirements from a requirements.txt file
Add 'pip_cache_path' config option for providing a local cache of pip dependencies
Add 'nagios_index_content' config option for customising the index page nagios check - so you dont have to edit playbook.yml
Default the 'app_label' variable to the unit name, so it doesnt need to be included in the playbook.yml
Add 'archive_filename' config option for specifying the archive filename in settings rather than playbook.yml
Move 'wsgi_application' variable to config.yaml instead of playbook.yml - for easier customisation
Add 'code_assets_uri' option to config.yaml
Declare 'code_archive' more globally so pip ansible tasks work
Clarify that code_assets_uri should *not* contain a trailing slash - this just burned me
