Support for Oauth 1.0

Suggested by @sanchojaf on Gitter:

we know OAuth 1.0 is not supported by Swagger 2.0, is possible and make sense add to patch.yaml ?

Hi, these APIs use OAuth 1.0 authentication:

1. thenounproject
2. audiosear.ch
3. slideroom

@maryguirola Thank you. It's very helpful.

@IvanGoncharov You're welcome.

@maryguirola One possible way to represent oAuth1 is to declare a securityDefinition of:

{
"type": "apiKey",
"in": "header",
"name": "Authorization",
"description": "oAuth1"
}

It would be up to the client to negotiate oAuth1 and build the Authorization header 'manually'. I'm thinking of doing something similar for Amazon AWS's HMAC security scheme.
