ID Timer v2.1.0

Release 2.1 of ID Timer replaces all previous release of ID Timer and Timer on the Tens. This release was developed with QML and C++ utilizing the Qt Creator IDE, thus replacing the previous development environment (Embarcadero).

1. Now available in both Windows and Linux editions!
2. Changed the selections by implementing a settings menu where all selections can be made from a single window.
3. Removed the callsign at the top of the app as well as removing the color selection functionality.
4. Included a couple of basic tones in the compiled executable for use if WAV files are not desired or not available.
5. Included the ability to change the timer expiration to 1, 5, 10, 15, 20 and 30 minute intervals for non-US hams.
6. Linux Users Note: Some distros do not contain the file "libxcb-cursor0". Run these two commands from the TTY if the timer fails to launch.
