Bug#749659: audacity: Please update to use wxwidgets3.0

Dear maintainer,

We're aiming to migrate the archive to using wxwidgets3.0 instead of
wxwidgets2.8, and intend to drop wxwidgets2.8 before jessie is released.

I attempted to rebuild the current audacity package by updating the B-D
on libwxgtk2.8-dev to libwxgtk3.0-dev, but the upstream source assumes
that wxGenericFileDialog is available, which is no longer the case in
wxWidgets 3.0.

As far as I can make out, Audacity uses the generic implementation of
this dialog because it wants to add an extra button.  I've filed a bug
with wx upstream to ask about the removal of this class, as this change
isn't documented in the list of changes since 2.8.  Here's that ticket:

http://trac.wxwidgets.org/ticket/16300

I had a quick look at Audacity's SVN repo but couldn't see any obvious
work towards wx3.0 support.  Do you know if they have plans for when
wx3.0 support will be added?

Cheers,
    Olly
