  - Merge "Apex: Explicitly define file paths"
  - Apex: Explicitly define file paths

    Due to bug with forbidden file paths conflicting with file paths this
    explicitly defines all the file paths in apex.  This isn't the greatest
    solution in the case where someone adds a new folder, but chances are
    they will also modify one of the other files as well.  Note it also
    fixes a bug where unit tests woudl run twice because it would be
    triggered as part of apex-verify-master and apex-unit-tests-master.
