Hello Developers,

this patch saves the state of the "LR Gang" buttons in a config/pref 
file, because this button's state is not preserved throughout runs of 
envy24control. At present it only works, when envy24control is compiled 
with GTK2 as I have used routines which were introduced with Glib2.

While this works fine I think we should discuss if envy24control 
could/should be compiled with gtk2 by default (currently gtk1 is 
default). As I think all Linux distributions now ship with Gtk2 and most 
other software uses gtk2 by now, I think it would be a reasonable thing 
for the next release of Alsa. This would also mean, that this patch will 
work with the default configuration :)
