[E-devel] bugfix for e16 crashing with sounds...

[<Val...@vt...>]

OK, so I started to wonder why e16 would segv every time I tried
to open the 'About Enlightenment' to check the build date I was actually
running...

Turns out that sometimes, the 'sound' resource isn't set.  And this
eventually lead to a crash trying to strcpy from a null pointer down in
SclassFind.  I'm going to bet that a lot of people never see this because
they get saved by the !Conf_sound.enable check just before....

(This patch *also* fixed a number of other mysterious crashes when e16 tried
to put up a dialog box..)
