Closes #82.

• pk is described by the Field(description=...) of the model's primary key field, else Primary key of the record.; an endpoint's own Path(description=...) is kept.
• offset, cursor and limit have descriptions; limit states the viewset's default_page_size and max_page_size.
• @endpoint_docs key parameters: descriptions by schema name, merged per parameter along the MRO; an unknown name raises ValueError.
• A list without a filter model publishes no fltr parameter (it was type: null). With a filter model, its fields were already published one per parameter with their descriptions.
• GET {base}/schema answers the named schema OpenAPIDocument and describes itself; overridable under the action name schema.
• Field descriptions on PaginatedList, CursorPage, LookupItem, LookupFilter, SortStateColumn, Change, RecordsChanged and the events viewset models.
• openapi_descriptions_test.py checks that every parameter and every schema field of a full viewset plus the events endpoints has a description.

Patch bump to 0.15.1 (Python and npm).
