Goodbye CoffeeScript!

[mohsen1]

• All CoffeeScript files are translated to JavaScript
• in OperationView class, some methods were too large to hand-code from scratch without making sure there is no code slips. The JavaScript generated by CoffeeScript compiler is used. There are comments in the file indicating that. We should refactor those large methods in the long run.
• Removed CoffeeScript from build task
• Introduced JSHint although as of now it's not passing all the tests because there are too many globals. I didn't want to add all those globals to JSHint config file and instead I want to namespace all Views under SwaggerUi object in a separate PR. Then we can add JSHint and possibly JSCS as part of build process.
• When rewriting files, I cleaned up some unnecessary code. Notably template functions that were returning only a value.
• Tests are passing on my machine.
