Once again the user can use the Font button on the toolbar to get the current

contents of the character dialog even if the dialog is hidden.

I think that the functionality of the character dialog/Font button on the
toolbar is now as it was in 1.1.6. Oh, but we now have a working button
controller that the GUI's get for free...

Keep up the bug reports!

+	* ControlDialogs.h added // -*- C++ -*-

+	* ControlCharacter.[Ch]: added // -*- C++ -*-
+	(setParams): Check contents of font_ to activate Apply button.
+	(clearParams): removed.
+	font_ is now stored as a boost::scoped_ptr.
+	font_ is no longer deleted on hide(), so it's contents can now be used
+	by the Font button on the toolbar.
+	Lots of new methods so that the GUI can easily get the contents of
+	font_ when it update()s.
