add exclude options

[steele123]

This gets rid of options displaying in the generated swagger, useful when using for example the CORS plugin when you have several options routes. Note: by default I set it to true as I believe very few people would want CORS in their swagger.

@steele123 Great idea! Maybe it should be more like "excludeMethods" where you can define a list of methods to exclude?

Potentially updating the current "exclude" to have an array of objects like this;

    exclude: [{
      path: "/api/",
      methods: ["OPTIONS"]
    }],

This essentially could exclude all paths with "/api/" and the method "OPTIONS".

ah yeah I think this overall better although most people would probably just exclude options but I like that

[steele123]

hmm only downside to doing exclude like that is it'd be a breaking change, for now i'll just make it is own array as excludeMethods: ["OPTIONS"]

@steele123 Sounds good! Good work
