[Patch-gnuradio] Patch for adding a refresh rate parameter in GRC Qt sink.

[Julien.Olivain]

  Hi,

  While using gnuradio (git master) on a Linux Fedora 17 i686 (32bit),
I saw that the refresh rate of the Qt sink was very slow (~2fps).

  I saw that in commit 3259e2a6, the update delay timeout was changed
from 0.1s (10fps) to 0.5s (2fps).  So my 2 fps make sense.

  As a quick workaround, I did the attached patch to be able to change
this refresh rate directly from GRC.

  I think the 10fps default was better than this 2fps.  If there is no
special reason for keeping this 2fps default, I also suggest to put it
back to 10fps.

  Regards,
