Adds dash/panel app templates, mgmt commands, template loader.

Implements blueprint scaffolding.

Using custom management commands you can now create the majority
of the boilerplate code for a new dashboard or panel from a
set of basic templates with a single command. See the docs
for more info.

Additionally, in support of the new commands (and inherent
codified directory structure) there's a new template loader
included which can load templates from "templates" directories
in any registered panel.
