TypeScript gets unhappy if you're mixing what it considers to be a "namespace" with ES modules, and can end up discarding a lot of type checking as a result. Their recommendation is that everything these days should be modules. Before we switched to modules, we were starting to try to namespace our code more thoroughly, and therefore everything inside the Djblets configForms bundle was namespaced into `Djblets.Config.*`. This change makes it so we export two names for each top-level item, `Djblets.Config.*` and `Djblets.Config*`. This allows us to import the `Config*` names from `djblets/configForms` without getting any warnings. Testing Done: - Ran js-tests. - Verified that the compiled configForms index.js file only had one copy of the definitions for the classes but was exporting them under both names.
