Check for updates when the headset app opens, and let Frametanium update itself

The headset app asks for a check (cached releases under 10 minutes old count) each time it opens; every check
then installs a newer Frametanium release without asking unless something else is installing
("self_update": false turns it off). Its version now comes from a VERSION file in the bundle, so its own row
is right however it was installed (deploy.sh included), and Update all does Frametanium last so the restart
can't cut off another install. After an update the list says to reopen the app.
