New Module: Gitdumper

[domwhewell-sage]

Ok this PR adds gitdumper as mentioned in #1707

Some features from githacker have been included in this module aswell

I have added the subsitution to the regex helper (I also added a function in gitdumper to regex in files / folders which may be useful to move to the helper)

The git module has been modified to emit CODE_REPOSITORY events.

gitdumper will then check if dir listing is enabled (And if so download it that way)

If not it uses a fuzzing list with common git file names and many common branch names, you can also fuzz tag names (Feature from githacker)
