Finish dispatcher-based modules.

* Implement ModuleWrapper for IE.

* Add JsParamFetcher::SetReturnValue(JsToken) for Firefox, which is needed
  so that GearsFactory can return dispatcher-based modules.

* Remove support for ISupports modules from JsCallContext. This was
  added because cdevries was thinking he'd use JsCallContext in an
  ISupports module, but we since have decided that it makes sense to make
  JsParamFetcher ISupports-only and JsCallContext dispatcher-only.

* Fix a bug in JsParamToToken for doubles.

* Add a stub for the DatabaseManager module (part of Database2) as a test.
