Add a call helper

[Ectropy]

The W5 status page should have a text field where it shows a "Call helper"--suggested text for scouts to use when sharing the info in RS

For example:
w5 | North near Draynor Manor | 45% | 15 minutes til dead by lightning
w104 | Near elves | 27m
w84 | Close to Yanille | Sapling Oak

Partly implemented in 815bafc

We should also allow a person to view the suggested call without copying.
