When serving JSON responses, replace "Not Found."

[HalosGhost]

Right now, even when the client has been set to accept JSON (and therefore expects valid JSON), a GET or DELETE on a paste that does not exist returns the string Not Found. While this correctly conveys the error, it is invalid JSON. I would propose the following response to keep in-line with the other responses:

{"status": "nonexistant"}

14:41:46 +buhman halosghost: that would only work if you expect the paste content to also be encapsulated in json
14:41:49 +buhman is that what you want?
14:42:18 +halosghost no
14:42:23 +buhman then not a bug
14:43:01 +buhman if you want to interpret the response, use the http status code

[buhman]

You're right; DELETE and PUT should definitely always serve complex_response() and not lazy plaintext.

Fixed in ae5d8ef.

@buhman, something is still a bit weird here:

In theory, both of these should be using complex_response(). Is there a reason that /ls isn't obeying the Accept header?
