create schema editor component

[matt-cook]

Create a shared component that gives a form (generated from the provided schema) editing UI with parameters for: content-schema (json), ui-schema, on-edit, on-submit. Should use https://github.com/json-editor/json-editor and vanilla css/js. Jquery and Bootstrap (bootstrap only if absolutely necessary) can be used if needed.

Example schema is here: https://github.com/lookitscook/kiosk/blob/master/schema.json

Additional UI schema file may be required to control settings related to form field visibility, grouping, etc.
