Changed format for specifying inputs: separate into base_dir and file_pattern. This allows us to handle the cartesian product more efficiently. Added Config#compute_glob_pattern.
Refactored CLI import commands to eliminate duplication
Refactored arguments to Utils.move_files so we don't need #base_dir_from_glob_pattern any more.
Added more checks to make sure config vars comply with naming conventions of ending with '_dir' and '_files'
Extracted repositext-cli into separate gem
