New glyphs and cost system

[StellarWitch7]

Added five new glyphs, four distortions and one ploy. Will be starting work on making tricks cost mana.

[StellarWitch7]

All living entities now have a mana pool based on their maximum health. Ploys now cost mana and will drain the caster's life in place of mana if there is not a sufficient amount available. Living entities regenerate mana at a slow rate.

Planned items:

• Glyphs to view mana levels.
• Glyphs to link other entities as a source of mana.
• Give spell circle entities a mana/sec just as living entities have.
• Wards to manipulate player-targeting ploys.
• Make calls to wards easier.
• Tweak mana costs and regen values until satisfied. Good enough for now, we'll see how it goes.

[StellarWitch7]

Mana values are still needing some tweaking but I'm marking this as ready for review.

[StellarWitch7]

Put this back into draft due to serious balance issues.

[StellarWitch7]

Instant death spells have now been made far more difficult to use.

[StellarWitch7]

We're ready to merge! Nevermind, forgot about armour stands having a mana pool.

[StellarWitch7]

Armour stands no longer have mana or blood mana. We're now actually ready to merge.
