HumBLE Explorer 0.4.0: Minor user interface improvements

This release adds some minor user interface improvements. The description Unknown for unknown company IDs and UUIDs is now shown in red. If the Bluetooth address has a known OUI, the vendor name is shown. And the number of filtered and received advertisements is now shown in the title.

The documentation now also tells what to do if you want to contribute descriptions for unknown UUIDs. You can contribute these to the bluetooth-numbers project.
