Hotfix for switching to shields

Better optimization; switching to shields works without glitches; can use menus to switch weapons.

Fixed bow/crossbow switch glitch; shield+1h weapon>bow>shield+magic should be fixed now

Fixes small issues with left hand weapons while dual wielding.

Crossbow/bow collision fix removed due to enchantments loss; configuration spell added.

Reverting from beast/vampire form should now be fixed; Power spell has now permanent effect (Off by default)

Script performance fix.

Minor bug fix when switching from magic to weapon

Slot 45 version

1. Fix for Vanilla game Followers. (Fail)
2. No slot requirements

For screenshot purposes.
To "gear up" your followers, take all follower weapons away, then give them weapons you want to gear them up with. It is important to give them ranged weapons BEFORE melee weapons, otherwise they might take bows off.

Followers are fixed (they show proper models when unsheathing weapons now)
Dual wielding fixed
