switch-on-connect: add option to ignore virtual sinks/sources

Browse source 
module-switch-on-connect would switch to any new sink, even if the sink
was a filter or a null-sink.

This patch adds a command line option ignore_virtual to the module, which
lets module-switch-on-connect ignore virtual sinks and sources. The flag
is true by default because the purpose of the module is to switch to new
hardware when it becomes available.
