Changes in v1.1:
- Do not crash on invalid button number events. Inform the user once and continue with reduced functionality in the button UI.
- Detect and inform the user about a mis-compiled binary with missing data files, instead of crashing.
- Fixed crash when clicking on the serial device checkbox, while the serial device is not configured.
- Fixed visual inconsistencies in widget placement.
- Build compatibility improvements (mostly for clang and FreeBSD).
