Colin Walters db6caac9cc ShellWindowTracker: Follow transients for focus app 
As a side effect of (see bug 642221), we no longer put docks or
transient windows into the hash table mapping windows to apps.  The
"focused application" code relied on at least transients being in
there.

Fix this by calling the public API to map a window to an app, which
will at least follow transients.  Whether we also want further
matching here (e.g. with window grouping) is another issue, but that
can happen as a different bug.
