updated location icons

[mblauser]

replaced known locations with 📍 and unknown locations with 🌐 to send request

Would it make more sense to use this 📍map pin for known locations?

I believe the 📡 icon has some degree of confusion for what it represents. I recommend re-using 🌐 for requesting locations.

In the current build I have updated the title of 🌐 to be "Fly to" and no longer sends a request position request to try and cut back on traffic. It was originally there to try and keep information up to date, but users are valuing lighter traffic in busy environments.

I considered maybe using Ctrl or Shift when clicking the globe to send a position request, but that wouldn't be obvious.

If we keep the request position icon there when the position is known, perhaps we then include 📍map pin, but I also like to use a little space as we can.
