Stereo System 1.7

1. Added the ability to dynamically calculate the duration (in seconds) of .mp3 and .wav files to enable detection of the end of a track's playthrough, thus allowing for the next track to be automatically played without user input.
2. Added an error message that will display if duration calculation failed.
3. Added a warning message that will display if an .mp3 file has been detected to have an MPEG-1 Layer I frame which appears to not be supported by FMOD.
3. Added repeat mode functionality which enables a single track or the entire playlist to be repeated.
4. Added the ability to decode ID3v2.3 and ID3v2.4 from both .mp3 and .wav files to obtain a track's meta data which includes title, artist, album, track number, genre, and year.
5. Added the ability for it to detect if .mp3 and .wav files have been removed from the music folder.
6. Added a default music folder in the root directory of the mod to make installation simpler.
7. Fixed a bug that caused the currently playing track to not resume playing after turning off the engine and respawning the vehicle.
8. Fixed a bug where pausing and then unpausing a track would cause it to not resume at the expected timestamp.
9. Fixed a bug where muting and then later unmuting a track would cause it to not resume at the expected timestamp.
