Start work on basic CLI features

+ Add basic logic for detecting conflicting configs, prompt to abort or
  continue
+ Create symlinks to configs
+ Basic usage is `kot path/to/dotfiles/`
+ Add `--backup-dir` option for setting directory for backing up configs
+ Default backup-dir to `backups/kapper` until finished testing
+ Add `--home-dir` option for setting location to install configs
+ Default home-dir setting to `dry-runs/kapper` until finished testing
