Update Swagger UI assets to v1.1.7

The latest tagged release of Swagger-UI, version 1.1.7, includes fuller
support for models, response codes, and syntax highlighting, and
includes fixes/improvements for some image references, etc.
Add models and responseClass to SwaggerApiService

The Models property in ResourceResponse, and the ResponseClass property
in MethodOperation, allow the Swagger UI to display schemas and sample
JSON for complex request/response types. The model data is generated by
reflection on request and response DTOs and inspection of
ApiMember/Description/SwaggerAllowableValues attributes. To use this
feature, define one ApiMember attribute with ParameterType = "body" and
DataType = "<class name of your request DTO>", and mark the request DTO
class with the IReturn<ResponseDTOClassName> interface. Also, ensure
that the Swagger UI js/css/html is up to date.

StaticFileHandler improved Range support.

StaticFileHandler.cs:
-"Accept-Ranges: bytes" was not set which resulted in IE not being able
to seek videos.
-If user seek video Chrome sends header "Range: bytes=5000-" which
resulted in sending whole file because "rangeEnd != fi.Length - 1" was
true but rangeStart was not 0.
-Ignoring exception "An operation was attempted on a nonexistent network
connection" because it just means browser disconnected
MimeTypes.cs:
-Added most common video types(mp4, ogg and webm)
EndpointHostConfig.cs:
-Added mp4, ogg and webm to AllowFileExtensions as default
