Feature Request: `--forms` parameter

I have noticed that your software is really similar to sqlmap in the design.
There is one thing that would be real neat is having the crawler parse POST forms because, right now if we crawl, it ignores that.
I can't afford to manually retrieve all forms of a website and launch one session for each.
Sqlmap does that when crawling.
Also it seems like issue #921 should be easy to fix.
