[Add] Four Horsemen of Naxxramas Marks

[K0lonel]

Not really sure how to add these to your release in a pull request so I added some dummy lines with id:50000 to visualize and hope you can add those.

1. duplicated DangerZone_W35_S30.m2 and gave it DangerAreaPurple.blp as texture
2. used id:4930 - "Arcane Anomaly Area" from SpellVisualEffectName.dbc and its links as model for my case in all affected files

I appreciate the time you put into this but won't be using it. My two issues with indicating 4hm mark ranges are that they're a little bit too close to cheating given that marks are an integral mechanic of the fight but much more importantly they are very noisy/distracting which is worse. If you find this useful that's really great but if I made everyone use this it would cause a riot of annoyed people wanting it off their screen.

I understand and you are right.
Maybe I will look for something less controversial like the spell=52797 from Timbermaw raid, tried to fully copy the spell effect from Kruul on it but didnt test it yet.
