feat(syntax): override module name parsing

Provides syntax to allow the overriding of module names, which is
broken in the case of modules containing periods (a common convention).

Example:

```js
/**
 * @ngdoc function
 * @name ui.bootstrap.$modal.ModalInstance
 * @module ui.bootstrap
 * ...
 */
```

Using the module name parser, the module name would end up being 'ui'.
However, this is not necessarily acceptable for projects like this where
the module name contains a domain-name looking pattern to denote the
type of module / package and authors, as well as the package name itself
and finally sub-package components.

In short, this feature is somewhat necessary, unless changes are made to
the syntax to use the directive-style syntax (or similar) for each and
every object type.
