OBS Python Multi-Counter Script with Sounds v1.3

I have added sounds to the hotkey's, you can now specify a sound to play when you increment, decrement or reset a counter.

I also did a general code reformat, so it should be more readable now.

I fixed issues with the formatting function and added locale so that the system decimal is correct.
Also added a property to specify number of decimal places.

I found that this script was not saving the decimals from the settings. Upon investigation I found that I was saving the numbers as int's and not doubles. I have fixed this and now the decimal places will be preserved when saving.
