Symbolic link fix

To test out Subuser, I cloned it into my $HOME and made a symlink from $HOME/bin/subuser to $HOME/subuser/bin/subuser. When calling subuser, it gives this error

Traceback (most recent call last):
  File "/home/a/bin/subuser", line 12, in <module>
    subprocess.call([os.path.join(subuserDir,"logic","subuser")]+sys.argv[1:])
  File "/usr/lib/python2.7/subprocess.py", line 522, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

This is to fix that problem.
