Many unit tests fail to load because they can't find their modules:

Traceback (most recent call last): 
  File "tests/window_xlib_test.py", line 8, in <module> 
    from winswitch.util.simple_logger import Logger 
ImportError: No module named winswitch.util.simple_logger 

Perhaps there is a more elegant way to fix that what I did in the attached patch, but it works for me.

Thanks.

Please ship RELEASE-NOTES in source archives.

(Current 'winswitch-0.12.14.src.tar.bz2' do not have 'RELEASE-NOTES' file.)

As reported in ​https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=772390

checkbashisms (from the 'devscripts' package) found the following:

possible bashism in ./usr/lib/winswitch/bin-override/xdg-open line 28

Not using bash (or a Debian Policy compliant shell interpreter that doesn't provide such an extra feature) as /bin/sh is likely to lead to errors or unexpected behaviours. Please be aware that dash is the default /bin/sh in Debian.
