MythicMobs - ChargedCreeper, CrazyHillary, MeteoriteCreeper, ThornedZombies Fixes

[Silverbane]

• ChargedCreeper does not explode when hit it just disappears. Needs updated drop table.
• CrazyHilllary needs more hp and few more abilities but also when Monica spawns explosion needs to be nerfed so it doesn't do explosion damage it just spreads fire. Also slow it down so people know whats happening. Needs updated drop table.
• MeteoriteCreeper Test Randomspawn, Needs updated drop table.
• ThornedZombies run one more balance tweak to remove thorns only on line of site, but reduce the chance instead maybe?

Note never updated drop tables.
