utf8: implement utf8foldernames option

Browse Source 
If utf8foldernames is enabled on account level all folder names read
from the IMAP server will immediately be reencoded to UTF-8. Names
will be treated as UTF-8 as long as the IMAP server isn't contacted again,
for which they are reencoded to IMAP4-UTF-7.

This means that any further processing such as nametrans, folderfilter
etc. will act upon the UTF-8 names, which will have to be documented
carefully.

NOTE 1:
GMail repositories and folders inherit from the IMAP... classes, so I don't
know yet if these changes have ugly side-effects. But web research suggests
that GMail IMAP folders are equally encoded in UTF-7 so that should work
identically here and incorporate the same improvements.

NOTE 2:
I could not test the behaviour with idlefolders as I didn't get this option
to work at all, not even with the latest stable version.

NOTE 3:
I *did* test to sync an IMAP repository against another IMAP repository.
