This commit renames the `static` attribute to `namespace` and simultaneously reduces and expands the scope. The `namespace` attribute can now be applied to all imports in addition to functions, and it no longer recognizes full typed paths but rather just a bare identifier. The `namespace` attribute will generate a Rust namespace to invoke the item through if one doesn't already exist (aka bindign a type).
