Cleanup old methods

[jbrichau]

• Removes old code mentioned in issue #1417
• Removes GRPackage extensions. This mechanism for declaring dependencies between packages pre-dates the Metacello configuration and baseline. It's no longer up to date and unused.
• Remove broken WADevelopment>>#cleanupCategories (see #1343). This can now be better handled via code critiques as well.

Maybe I'm missing something here. Unfortunately we still have some senders of GRPackage class >> #grPackages

• JQUiFunctionalTest >> #packages

Yes, that was not so good... just did not check those.

• In the functional tests, I replaced its use with something completely different (country names and currencies) to ensure these are not dependent on a specific platform.
• In WADevelopment, I removed the methods that referred it. None of these have been in use for the last 10 years and are replaced by either Metacello or code critiques in Pharo.
