Allow empty parameters

[kaleidocore]

Parameters in neither URL nor body can be left empty. Apparently something in the parameter substitution goes wong when I try, and the UI reacts badly to such attempts. I suggest checkboxes to either:

• set "empty" value (disabling the text input)

or

• allow empty value (stop warning about empty parameters, accept empty string)

Either related to or a duplicate of #105 , but I'm making a separate issue due to ambiguous wording.

Thanks for reporting. I'm not sure I fully understand the issue, yet. I can send a request like this successfully:

The ends up being http://example.com?q={a}&c and the body is just n.

Does the same work for you? What would you expect to happen instead?
