✨ bump to v0.1.5

This works okay on my home network, but it's a little more magical than
I wanted - I can't force it to pick up the wifi interface. If the
Ethernet is plugged in, the laptop always and only picks that, even
if I know the server only asked the Ethernet interface.

This is fine, but only because my Ethernet happens to be faster than
my Wifi. I'm not sure how it will behave at work, where WiFi and
Ethernet may be separate networks.

At least the error messages are better now, so I can figure out why
it wasn't auto-starting with systemd.
