Update dirty repo check to not include config files

[mikewoodward94]

Currently always need to use --ignore_git_check as config files are always different to those on repo (due to passwords).

Now config files are ignored and this flag shouldn't be necessary.

Looks good to me @mikewoodward94
Just one suggestion: can we ignore the entire config/ folder instead of individual files?

I personally have more than 2 config files in my config folders for most of my projects, and that would allow us to be more flexible
