Pyqt5 (#11)

* Ported TrezorPass to from Python 2.7 to Python 3.4+. 
* It works now on both, Python 2.7 and Python 3.4+. 
* Ported from PyQt4 and Qt4 to PyQt5 and Qt5. 
* It does no longer support PyQt4/Qt4.
* Unicode character can now be used everywhere: groupnames, keys, passwords, comments, csv import fields, csv export fields, etc.
* Bug fixes: csv export did not handle "\ pattern correctly
* Miscellaneous improvements. 
* Improved inline documentation
* improved logging

+**Question:** Can I migrate from Python 3 back to Python 2?
+
+**Answer:** TrezorPass runs on both but the implementation of `pickle` is different on both versions.
+The TrezorPass passwordd database file uses `pickle`. When you move from Python 3 back to Python 2 and
+then want to run TrezorPass, you will get the error message `Critical: Could not decrypt passwords: unsupported pickle protocol: 4`and the program aborts. The workaround is to export your database to a CSV file in Python 3, then start with
+an empty database file in Python 2 and import the CSV file. Then you are ready to go.
