As in subject: use SwaggerHttp from swagger-js class to handle file uploads.

Hi, after testing this, I'm not getting any content being sent to the server. If my memory serves correct, this is why we were using jQuery for file uploads. If you apply this patch, and try to upload to the petstore server (http://petstore.swagger.wordnik.com/api/api-docs), you will probably see this:

Uncaught TypeError: undefined is not a function shred.bundle.js:1243
createRequest shred.bundle.js:1243Request shred.bundle.js:847
Shred.request shred.bundle.js:388ShredHttpClient.execute swagger.js:1447
SwaggerHttp.execute swagger.js:1249
OperationView.handleFileUpload swagger-ui.js:1804
OperationView.submitOperation swagger-ui.js:1722
p.event.dispatch jquery-1.8.0.min.js:2
p.event.add.g.handle.h jquery-1.8.0.min.js:2

Right, I should have passed useJquery to true. Will adjust it the PR.
Thanks for reviewing this.

@aurelian Please make a PR with your changes to develop_2.0 branch.

Actually this support has been added in 2.1.8-M1 or higher of swagger js. The front end code does not call it yet because of missing support for 1.2 spec file uploads in swagger-js. So I suggest closing this pr

[aurelian]

Yup. Good to close it.
