Update 5.6.19

Almost done, a bunch of fucking item and crafting tooltips left to to
do.

List of changes:
UPDATES
- mana crystal removed from crafting recipes: the recipes that once used
it now require mana stone (sniper gun, empowered spells);
- Arcanums reverted back to single spell usage; passive bonuses removed;
- all fur and leather coats now provide 10% penetration protection and
improved armors provide 10% more penetration protection;
- energy cost for shaman voodoo revive increased twice (now you need
full power to revive a bear, alligator or troll zombie);
- all weapons rebalanced: melee critical mechanics replaced by melee
damage; power hit damage amplitude decreased (weak weapons are stronger,
strong weapons are weaker); throwing weapons power damage increased;
BUGS
- the bug when picking random troll has been fixed
