PulseAudio: allow monitor devices to be used as inputs.

PulseAudio automatically creates monitors for devices.
These devices were previously explicitly excluded from the
list of input devices by Mumble. Excluding these devices
blocks people from combining multiple streams into Mumble
via PulseAudio.

One possible scenario is listed below:

 Requirement:
  - One wants to combine headset input and sound output
    of a script into mumble.

 Solution:
  - With PulseAudio one creates a virtual sink. Let's
    call it "vscrd1".
  - The headset's input is looped to "vscrd1".
  - The script's audio output is directly directed to
    "vscrd1".
  - Mumble is configured to use the input device
    "vscrd1.monitor"

Now one can talk and send sound to Mumble at the same time.
It also helps much when using sound bots (music etc.).
