Fixed crash when starting quickly #9

xprop.py assumed that xprop always would find _NET_ACTIVE_WINDOW, which can be false. Usually when no window is focused it becomes 0x0, but that variable seems to be defined upon window unfocus so if aw-watcher-window starts before any window has been focused it used to crash.

Looking good, go ahead and merge when Travis is done.
