MagazineAsset property table

[MoltonMontro]

Rewrites the doc for ItemMagazineAsset to use a table for properties -- following the same formatting as other recently-updated docs.

Also fixes the terms used for certain data types in a couple docs (e.g., "float32" and "uint8" instead of "float" and "byte".)
