Title: Databinding updates

Includes fixes for:

#392: Clarify what's observed in polymer expressions.
#413: Doc auto-binding templates.

Adds live sample for auto-binding templates. Includes a small fix to include_external.rb, which didn't support region tags that included a dash (for example, `doc-sample`, `runnable-sample`).
