adding conditional url-encoding, fixing xml parameter extraction bug

[liquidsec]

This PR fixes this bug: #2182

And also changes the way url-encoding is handled within lightfuzz. Now there will be default url-encoding for all outgoing probes, but submodules can opt-out, and we also do not enforce when any envelopes are present.

I also tweaked the regexes to allow for the extraction of parameters with spaces, which in light of the above changes, can now successfully be used without any issues.

Various tests had to be refined. Mostly because they weren't dynamic enough, I was hardcoding the existing URL-encoding into them when I should have them act more like a real server and decode before checking
