Fix supported submit methods in order to suppress the Try button

The option supportedSubmitMethods passed to the SwaggerUi ctor has been ignored since @09be20c97d, which seems like an accident or unfinished work for the 2.0 development branch.  This is a suggestion how to fix the #348.

The @e62cffc1e8 contains the actual change, the @ddb365929c files modified by running `cake dist` afterwards.  (I use less 1.4.2 and handlebars 1.0.12.  Let me know of you want to include the compiled result in the change or not.
