The password reset daemon wasn't being closed on restarts, so an extra
pwr would be sent w/ every restart. Restarts & Interrupts (Ctrl-C)
rarely worked, as there were multiple listeners to the "RESTART"
channel, and I didn't know the message was consumed by whoever got it
first, meaning if the main thread didn't get it first, the app wouldn't
quit. Listeners are now registered, and the restart message is
re-broadcasted until everyone's got it.
Fixes#264
"-H=windowsgui" disables stdout on Windows, and the io.Multiwriter used
for logging had stdout as it's first entry, which failed and caused
logging and line caching to be skipped. stdout is now removed from
the multiwriter in this situation. Other portion of the issue was
because crash reports had colons in their names, which Windows
doesn't like. Fixes#168.
Since an invalid example config was created on first run, if the app restarted
before setup was completed, it would crash on the next start. The
example now has a "first_run" flag in it, which is only set to false
when the config is modified. Also fixed restart at the end of setup for
tray builds.
