Lightfuzz - Try POST as Get feature

[liquidsec]

This PR adds an optional feature to lightfuzz (off by default, but on on medium and above presets) that automatically tries every POST parameter as a GET parameter. Interesting behavior can occur sometimes when this is done, which can sometimes expose hidden vulnerabilities. Especially interesting when POST's are disabled, allowing the found POSTPARAM events to still be used.

Also adds the other direction, try GET as POST. Same concept in reverse, added to heavy and up presets.
