Renaming to 4.0
Since we're renaming 3.7 to 4.0, we might as well take the opportunity to clean up parts of / some of the following points:
- package names: there's inconsistency in our package namings, esp. with regards to info.magnolia.cms.*
- deprecated code: there are loads of classes which have been deprecated since 3.0 or 3.5, it's high time we really get rid of them (todo : list them and provide replacements - see MAGNOLIA-2245@jira)
- version handlers: our version handlers still handle all versions since 3.0. The core mvh could use a whole lot of cleanup, esp.
- consolidate all export/import/backup tools
- remove stuff that (probably?) doesn't work anymore ("Redeploy the files in the classpath" etc) or reimplement them.
