Swagger UI doesn't send POST requests when clicking Try It Out button

[hamx0r]

The "Try it out!" button sends GET requests properly, but not POST requests. Per wireshark sniffs, no data is set, meaning, it's not a matter of erroneous data. This seems to be the case where paramType is query, body or header. Other values for paramType not tested. It seems like the form submission code is defined in swagger-ui.js in the OperationView.prototype.submitOperation function, but it simply calls model["do"] which doesn't seem to be defined.

Issue closed because "problem" was due to incorrect merging of merge_parameter_list. Added in fix to pull request #39
