Implement minimal macro namespacing and add tests This commit adds just enough namespacing to resolve a macro first in the macro's defining module's namespace (i.e. the module assigned to the `HyASTCompiler`), then in the namespace/module it's evaluated in. Namespacing is accomplished by adding a `module` attribute to `HySymbol`, so that `HyExpression`s can be checked for this definition namespace attribute and their car symbol resolved per the above. As well, a couple tests have been added that cover - the loading of module-level macros - e.g. that only macros defined in the `require`d module are added - the AST generated for `require` - using macros loaded from modules imported via bytecode - the non-local macro namespace resolution described above - a `require`d macro that uses a macro `require` exclusively in its module-level namespace - and that (second-degree `require`d) macros can reference variables within their module-level namespaces. Closes hylang/hy#1268, closes hylang/hy#1650, closes hylang/hy#1416.
