"queue with parameters" - introduce parameter types

[mchwalek]

Hi, I think the "queue with parameters" feature would be more convenient to use if we introduce a notion of type to the parameters. Firstly, because the currently used single-line inputs are convenient only for simple string data - passing something like a JSON is inconvenient and error-prone. Secondly, because the form passes all the parameters as strings, which in turn must be parsed by the queued job - it'd be more convenient the just receive the data without any conversion.

For my personal uses, I'd need the following types

• string (the default if type is not specified) - has the current behavior
• text - renders a textarea, passes value to job as string
• json - uses some js library to render a JSON editor, passes value to job as a hash

Please let me know what do you think about this suggestion
