Multiple expectations in a single request

New option: Put multiple expectations into a single request.
You can now send a top-level "expectations" element that is an array of
expectations. The full request would look like:
{
"expectations" : [
{ "path" : "totest",
"uuid" : "UUID",
"code" : 200,
"times": 1,
"response" : "first"},
{ "path": "totest",
"code": 200,
"uuid": "UUID",
"times" : 1,
"response" : "second"}
]
}

The old form of just posting one expectation also still works.
Delete by UUID

Can now delete expectations for a UUID and remove all expectations for
that uuid. You can also combine it with path and delete all expectations
of a particular path or a particular UUID (or both). Now there's a uuid
optional parameter when deleted. You can also delete with POST to
/mock/delete
Static pages added

Can now mark an expectation as static (boolean) and it will no longer be
subject to call times or expiration over time. That path will always
return that data until the server is restarted or a manual delete is
called.
