update version in setup.py

Merge branch 'master' into debian

Assword 0.7 release.

Debian Assword 0.7-1 release.

add enhancement TODO about browser url sniffing

database version 0→1 transition script

the ./trans script takes two arguments, the first is the old v0
database and the second is the path where the new v1 database will be
written, e.g.:

  mv ~/.assword/db{,.old}
  ./trans ~/.assword/db{.old,}

This script will be removed after the 0→1 transition.

the assword library has a hard dependency on Tkinter

remove build/install targets from makefile

again cause they were causing debian problems.

import xdo module on if needed.

This relaxes the xdo requirement.

remove comment of wait_for_window_focus()

A bug was fixed in python-xdo that was preventing this from working.
