Minor accuracy tweaks

Now you can spam single-use augments out of combat. They won't lock up unless you're in combat, and still only refresh at the start of combat.

Fixed slingshot augment working on ranged attacks (TWP shurikens, for example)

Fixed bad damage calc in machete aug

Fixed XP Gem augment incorrectly being able to pierce Negate.

Buffed Dud weapon augment

Added Goggles. +5% Acc multiplier when slotted into worn armor.

Tooltip cleanup

Reverted accidental Blunderbuss augment nerf

Cleaned up item re-definitions.
Removed Empower Augment compat from the "item stuck to a weapon"-type augments (blunderbuss, machete, slingshot)
Added compat for upcoming Slingshot Knight mod (WAugs should be loaded AFTER Slingshot Knight for maximum compatibility. At worst, the item description looks weird)
