added major C improvements

   * use libinih to read config file
   * handle SIGPIPE gracefully (when a trayicon exits)
   * exit when both trayicons have exited

I wanted to try using libini-config5 but it was not documented at all,
and I need useful examples.

- * Title: Proof of Concept C utility for polling capslock and numlock
- * Purpose: Demonstrate these can be done in C, with the eventual goal of rewriting keyboard-leds-trayicons entirely in C to avoid the "sleep 0.75" in ps output

- *    minimum viable product

- *    Write main keyboard-led-trayicons logic, which includes parsing config file (libconfig?)
- *    Write pipe connectivity to mktrayicon or integrate it entirely
