Add config option to ignore Pulseaudio Sinks

[IsaacWoods]

This adds a new config option, ignored-sinks, for the Pulseaudio module, which can be used to stop certain sinks (in my case the EasyEffects sink) from appearing. This is needed as these sinks are always running, and so hijack the volume indicator in the bar.

Example config:

"pulseaudio": {
    "ignored-sinks": ["EasyEffects Sink"]
}

Nice, can you add this feature to the man?

[IsaacWoods]

Sure, done. I'd also be happy to add an entry to the wiki once this is merged.

Hi @Alexays - I've rebased this against master. Is there anything else blocking this being merged?

[ChrisLane]

Would love to start using this @Alexays!
