Compare Parsing results on a given library with Karaoke Applications

[MacLemon]

Describe the bug

Using different applications with the same song library may result in a different count of parsed songs.

Steps to Reproduce

1. Take a song library
2. Parse with KaraokeV2 Queue software, take not of the song count
3. Parse the same library with Performous
4. Parse the same library with Ultrastar Deluxe
5. Compare the three counts and make sure they're equal.

Current behavior

There are differences in the number of recognized songs.

Expected behavior

All applications come up with the same result.

Notes

This only applies to libraries where all .txt files guaranteed UTF-8 encoding.

Sidenote for Tone-Deaf-Tools:

• Adding an evaluation function if a song SHOULD be a functional thing would make sense.

Current check with 10k Library:

• Performous: 10004
• KaraokeV2: 9768 Will investigate if I can find a pattern for the delta.
