Even when validate or build fail

With the changes coming in #33, we're in a rather cool position where we can host our schemas on GitHub:

models:
- github: devrel/blox/schema/profile
- github: devrel/blox/schema/article
- github: devrel/blox/schema/page

Allowing drb consumers to pick and choose their own models.

How do we want this to work?

Serious thought needs applied to Foreign keys and relationships, as we don't want to manage dependencies.

remove hard-coded templates, add file templates to the new command.

add a drb version command that reports the version

Support loading YAML/YML files from source and skip convert stage

support the new command creating content from user provided type-specific templates.

Add a build command that converts, validates, and outputs JSON

type to represent blog posts and other syndicated content

Add initial content templates
