s/dump/dumb/s?

* **Discovery**: to discover presentation devices, the controlling user agent should use the same technology as the presenting
user agent uses to advertise itself. **Potential technologies**: SSDP, mDNS or BLE (BLE Beacon)
* **Launch**: after discovery, the controlling user agent should know how to launch a new presentation or join an existing one.
Common message formats should be also used. **Potential technologies**: DIAL (uses SSDP for discovery), Google Cast (part of it).

We should specifically call out the HBBTv 2.0 spec (referencing GH Issue #67). User agents that support it will be able to present arbitrary URLs (not just pre-installed DIAL applications).
