webRequest block rule simplification (maybe)

[jacqui]

I was thinking the webRequest block could be a little simpler and/or streamlined:

• use a single field for specifying the url, whether it's a literal string url or a path to find the url in incoming data
• display the bodyPath only when PUT and POST are selected as the method
• order the rule fields in the UI like this: URL, Method, Headers, (optional) bodyPath

What do you guys think? I haven't decided if this approach makes it easier to understand and work with this block or more complicated.
