[Patch-gnuradio] Get framerate for waterfall/scope sink from user prefs

[Stefan Brüns]

Hi,

this patch adds framerate support for gl versions of the mentioned sinks. The 
waterfall sink uses the same key as the fft sink (same behaviour as the nongl 
versions), the scope sink uses a new key 'scope_rate', as the gl scope sink 
does not support fixed rate decimation, but supports a frame rate as the 
other two sinks

Patch affects source of the two sinks as well as the config file.

Stefan
