[Debconf-video] [patch] Improve dvswitch error handling and package README

[Petter Reinholdtsen <petter.reinholdtsen@usit.uio.no>]

I just tested dvswitch, and discovered a minor problem.  When running
it, it reported a non-informative message and aborted:

  % src/.objs/dvswitch -h localhost -p 12345
  terminate called after throwing an instance of 'Glib::FileError'
  Aborted
  %

I tracked this down to the lack of catch statement for the
Glib::Exception class of exception.  At the end is a patch changing
this to report this message instead:


  % src/.objs/dvswitch -h localhost -p 12345
  ERROR: Failed to open file '/usr/share/dvswitch/video-source.png':
    No such file or directory
  %

The reason I got this error is that I have not installed the Debian
packages, just trying to run the program from the source directory.  I
realize that it isn't written to work that way.

While trying to report this issue, I discovered that the README is
missing information on where to find the latest source and where to
report bugs and patches.  I guessed on a few settings, and include a
patch to add such information to the README.
