v0.1.5: creature comforts edition

• reworked a bunch of text to better guide new users
  • initial post-install steps should be clearer
  • render repo from-template is now friendlier!
• new command: render blueprint from-template will pull a Render Blueprint (render.yaml) file from an example and place it in your current repository. If you'd like to quickly deploy an application, you can use this to get started with a directionally accurate template.
• new command: render config add-profile lets you add another profile for use with the -p flag.
