Linux: Deb

What's changed

• Now supports notification sounds - idea courtesy of GuardiansAscend.
  • Program comes with a default sound, but you can load in one of your choice - if you exit the program as expected [by right clicking the icon and clicking exit] - then the loaded sound file will be added to a new file, the configuration.txt file, as well as the volume, this way - it will persist between loads.
• Fixes some bugs.
• Cleaned up the code a bit.
