Initial release.

caudec_droplet.cfg must be placed in user home dir.
(settings applied in here override the settings in an eventually present .caudecrc file when executing caudex through the application)

Some limitations apply at this point:
- Unnecessary display of 'Done' when starting the application up.
- Not possible to close the application by clicking the red circle in the top left, instead you have to choose menu-quit or press CMD+Q.
- Unclear behavior when copying multiple files, untested.
- Unclear behavior when trying to copy a file that doesn't exist, untested.
- Unclear behavior when output files of the same name already exist, untested.
