Merge pull request #70 from zfcampus/feature/docs-api

Feature/docs api
Fix route name

- s#rpc-service/rpc_input_filter/#rpc-service/input-filter#
Removed redundant file
Revised documentation edit screen

- modified to use pills instead of tabs for tab navigation, which required a
  change to ag-tabs to allow specifying pills vs tabs.
- added ag-comment, in order to comment out the "generate from configuration"
  buttons for request/response payloads.
- nested tabs, and placed tabs inside panel-content divs to provide some visual
  context.
Minor fixes to behavior

- larger textareas
- flash message now correctly references documentation, not input filter
Merge branch 'feature/documentation'

Close #70

This merge brings in the first stage towards the documentation milestone, and
includes the ability to edit and save documentation snippets for services, their
collections and entities, the request methods supported, and the expected
request/response formats for each request method.
