Bump Smoke to Edge

Need to bump for:

1. Better handling of inner controller classes (couple repos I know of are impacted by this)
1. More robust handling of filenames so that repos do not blow up during reporting phase

Initially I tried just including these two as patches, but was running into trouble, so just decided to go all the way to edge. There are some what Justin calls "breaking changes", which he said should be reflected in the 2.0 roadmap: https://github.com/presidentbeef/brakeman/wiki/Roadmap#20, which we'll have to look through and verify are ok.
