[Feature Request] Connect to rotator server by IP or hostname

[N7ILK]

First let me tell you this is an incredibly useful App. I have a homebrew rotator that receives data on an ESP32. It works great!
My internet router doesn't have a way to map MAC to IP and I'm getting a different IP assigned to the ESP32 about every 72 hours.
I've added mDNS on the ESP32 to give my device a "SatTrack.local" name and can connect from other devices (PuTTY) using that.
The "missing link" is a way to enter a name into the settings for Rotator Preferences and have the App resolve that to an IP.

Thanks again for the wonderful App. I'm really impressed with the quality of the software and its usefulness.
