Added Pyramid PQ

[Silwhoon]

I will need a lot of feedback for this change - it's quite a big one! ANY feedback/suggestions big or small are much appreciated.

• Added PyramidPQ solo & party handling
• Added Pharaoh's Blessing buff handling.. but the BERSERK buffstat seems to be bugged? It makes the player attack very slowly and does not grant any additional damage.
• Added Rage of Pharaoh skill handling
• Added GMS-like text & effects wherever possible. There are a few missing texts that I have labelled with a "TODO"
• Added GMS-like PQ handling wherever possible. Mob Respawn is not completely GMS-like. These have also been labelled with a "TODO"
• Added Bonus Stage handling - Including the 'skipping' functionality, drops & a fix to ItemRewardHandler
• Added handling for the Medal Quest.. but it seems that saving quest infoNumber progress is bugged..? Didn't want to address that in this PR

Appreciate the effort! Looks good on first glance apart from putting a bit too much into Character.java (which I'm trying to pick apart to make it less of a god object).
I'll have a closer look once I got more times on my hands. I hope you don't mind waiting for a review a while longer.

I have no issues with waiting however long you need. I will amend the code and try to reduce the code put into Character.java in the meantime
