Options Object - Not compatible with all valid URL and Method values

[clandestine8]

url and method in the options object do not support Functions as values, as it states it should in Dropzone.js's documentation.

Also URL is not a required value for Dropzone as it can be processed using a Function Method.

This also makes the documentation site inaccurate as it states...
A dropzone configuration object, accepts all valid dropzone configuration
which is currently not true.

This can be resolve by updating to a new version of dropzone. It may be a good idea to have to user provide the dropzone package in the future so it can be updated independently if there are no breaking changes.
