Changed 'Disable accuracy decreasing' label to 'Disable accuracy/mana decreasing'

Added `magichands_sv_global_manaregen_mult` convar

Changed workshop page to be less 40k (Gee W has been very litigious recently)

Made Vis dissolution far more reliable
Fixed Sana Magna resetting overmax hp and armor
Added global balancing variable magichands_sv_global_dmg_mult

Made ignis maxima boom sound effect slightly more reliable

- Sana Nidum and Castra changes : Made more transparent, no longer costs mana to dispel, constant mana drain while active, fewer particle effects

- Gave up on getting Sana Nidum to block projectiles properly (I think for the third time now?), so now it's just Sana Castra but with 1/10 the shield HP, smaller, and half the heals/repair. RIP
- Toned down Fulgar (zaps) sound effect volumes
- Toned down ira and sui dis aura/halo effects
- Fixed GLUA error caused by Malum on disconnects
- Increased aiming assist for single target Sana spells significantly (and gave it to Verus)
- An attempt was made to fix ignis maxima boom not playing
- Dis Vis Magna added, basically Dis Vis but just a huge wall instead
- Fixed Fulgar Ira damage ||Oh, you may not be aware, but this is basically Malum Ira lite: lifesteal and flat extra 500 lightning damage on melee||

Added fulgar ira

dis fix
