Switch to boot-time for timeouts
Flesh out README
Return only the result JSON from shoved-register
Improve errors in register
Move register from examples to bin
Implement exponential backoff for reconnections
Maybe make reconnection work

I haven't been able to test this since the connection seems to persist
even if I lose network
Make register command work with system daemon
Make system mode usable
Ignore NotFound when removing socket (since it might already be gone)
Add minimal (read: mostly useless) README
Somethat that really works
Something that might work
very temporary things
