Missing dependencies

```
Traceback (most recent call last):
  File "fractality.py", line 3, in <module>
    import tkinter
  File "/usr/lib/python3.4/tkinter/__init__.py", line 38, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: libtk8.6.so: cannot open shared object file: No such file or directory
```

What libraries need to be installed to run the script?
