More "wishes" for GRC

It would be convenient (well, beyond convenient, actually), if there
were a way to do init-time (not necessarily post-flowgraph-start)
reconfiguration at run-time. There’s currently a “disable” control
within GRC, but that’s a compile-time thing.

It would be nice to have a single flow-graph that has a few minor
variants, which can be requested at init-time.

For example, my simple_ra tool would be better if one could ask for
differential (two hardware sources) mode, or interferometer mode.
Right now, I have to use separate flow-graphs to do that, and
managing architectural changes among multiple flow-graphs that all share
a “core architecture” is a bit of a pain.

Also, unrelated to that, and I think I’ve raised this before. A gating
control on a file-sink would be great. Either a dynamically-changeable
or a separate “gating” input stream. Dynamically changeable
parameter seems like the least-disruptive thing to do if keeping the
existing filesink.
It would default to “True”, so if you don’t use that parameter, it
behaves as it now does.
