FR: Allow custom hostname

[mhanuszh]

Use Cases

Please allow us to specify the broadcast hostname in the Android receiver app.
I'm on a rpi5, and my fcast hostname is FCast-Raspberry-PI 5 Model B Rev 1.1, which isn't really useful.

Are you really using the android receiver on a RPI 5? If you do, I recommend to switch to the desktop receiver which can be installed from flathub https://flathub.org/en/apps/org.fcast.Receiver. I added your feature request in 0b2fcb1 and 1a992fe. It will take some time until the android receiver gains the same functionality.
