ENH: Changes in FontPropertyWidget and TextLocationWidget

FontPropertyWidget: Added opacity spinbox to control font opacity.
TextLocationWidget: Changed listening from the groupbox clicked()
signal to toggled() signal so that QtTesting tests can simply use
set_boolean command on the groupbox.

FIX: Fixed test using the new TextLocationWidget

QtTesting currently cannot record the event of activating a toolbutton to bring
up the associated popup menu. To work around this issue, just add a line before
the QtTesting recorded line to activate the toolbutton.
