Remove redundant options while switching to new Shadeless v2

• Remove redundant Shadeless URL options

Add static score column

Static score column is a heuristic column that score the request / response is static file or API endpoint.

The higher the score, the more likely the endpoint is a static file (which we do not need to see and forward to intruder).

We can also filter it by: Request.StaticScore <= 50
