Remove outdated docs

- These docs were originally from the PhlyRestfully module, and are completely
  outdated at this point. Removing them so they do not cause confusion.
Merge branch 'hotfix/docs-removal'

Removing outdated docs.
Corrected identifier name requests to route identifier name
All tests passing
Distinctly set the route_identifier_name to the AbstractRestController identifierName property
Allow composing the input filter into the ResourceEvent

- Allows composing a `Zend\InputFilter\InputFilter` into the
  ResourceEvent.
Inject the ResourceEvent with the InputFilter

- Added logic to getResource() to detect if an input filter is present
  on the resource. If not, it attempts to fetch it from the MvcEvent,
  and then inject it into the resource. The Resource now composes the
  InputFilter, and pushes it into the ResourceEvent during the
  prepareEvent() phase.
- Fixed CS issues.
Changed all identifier_name to distinct name
Merge branch 'hotfix/46'

Injects the ResourceEvent with the input filter found in the MvcEvent, if present.
Added accessor for input filter
Merge branch 'hotfix/input-filter-accessor'

Added accessor for input filter.

Distinct identifiers

Renames "identifier_name" to "route_identifier_name"
Override process(PostData|BodyContent) methods

- to use ContentNegotiation bodyParams() helper. Fixes an issue when using input
  filters due to the fact that php://input can only be read once.
Fix processPostData

- was not calling `create()` on the data fetched!
Update tests to use bodyParams plugin

- Since this is used by default now, it needs to be injected in the
  plugin manager.
- Also, for tests that require data in the request body, inject the data
  into the container.
