With Pidgin doubt there's much difference. Title has always worked fine for
me for this specific purpose. However, Title is a bit flakier in general,
since apps sometimes set title dynamically, or wait till after they're mapped
to set it. So overall I vote role better than title.

Didn't think of matching Role here simply because forgot that it's already
predefined for IM layout. If it were used in a manageHook instead, it would
have required an extra bit of explanation / definition.

role = stringProperty "WM_WINDOW_ROLE"
