Auf Python 3 portiert, Django-Abhängigkeit entfernt

- piccreate.py, utils.py: print, configparser, has_key -> in, UTF-8 I/O
- smart_str/smart_unicode entfernt, eigenes slugify() in utils.py
- configparser mit strict=False (doppelte [+] Sektion in den Font-cfgs)
- Shebangs und bin/piccreate auf python3
