Removed implicit Attribute extension from GuidAttribute

When applying an attribute, the `Attribute` extension is implied, and thus doesn't need to be included. While I was at it, I moved the `[Guid()]` attribute to the bottom, below `[InternalsVisibleTo()]`, for consistency with other `AssymblyInfo` classes.
