We passed in the accountname to all derivatives of BaseFolder, such as IMAPFolder(...,repository,...,accountname), although it is perfectly possible to get the accountname from the Repository(). So remove this unneeded parameter. Each backend had to define getaccountname() (although the function is hardly used and most accessed .accountname directly). On the other hand BaseFolder was using getaccountname but it never defined the function. So make the sane thing, remove all definitions from backends and define accountname() once in Basefolder. It was made a property and not just a (public) attribute, so it will show up in our developer documentation as public API.
