Allow passing per-test config values to the fake app
Fix typo
Allow passing form default values from a separate configuration file

 - by default does nothing

Added default value for doc unit rulesAndConventions field.
Remove test data (oops)
Enable default values on line inputs
CSS tweaks + formatting
Tweaks to prettify the concept form
