utext crashes when opening an empty file

[Michael Achmann]

When running the command to open an empty file with utext it crashes:

/opt/extras.ubuntu.com/utext/bin/utext README.md

************************************
None

Traceback (most recent call last):
  File "/opt/extras.ubuntu.com/utext/bin/utext", line 39, in <module>
    uTextEx = uText(filename)
  File "/opt/extras.ubuntu.com/utext/share/utext/utext.py", line 352, in __init__
    self.load_file(afile)
  File "/opt/extras.ubuntu.com/utext/share/utext/utext.py", line 655, in load_file
    ans = data.decode(encoding)
TypeError: decode() argument 1 must be str, not None

The same applies for opening a file via right-click menu. Without a file the Program is working fine, if the file is not empty its working properly as well.
