Official Release 1.0

This is the first (somewhat stable) release of Musicly!

Known issues:

1 - If a file that isn't audio is played using the previous or next buttons, the program will crash! This is due to me not figuring out how to identify the next index in the list and check whether the name ends with .mp3 or .wav or not using the NAudio library.

2 - The interface feels VERY sluggish and there's a small amount of delay sometimes when using the buttons though there are no issues in playback.
