QMailServiceConfiguration::encodeValue() is protected, making it more difficult to programatically change account details.

I have need to set/modify IMAP/SMTP details, as I'm writing a simple importer tool for accounts from another mail service to QMF accounts.

The problem I encounter is that some values should be encoded (like passwords IIRC), which requires QMailServiceConfiguration::encodeValue(), a protected member.

This isn't a problem within QMF itself, as QMF has various plugins which subclass QMSC, but it isn't quite so easy for me as subclassing is unnecessarily complicated for such a simple tool, so I would appreciate it if encodeValue() could be redefined as public API.

If you need more information (or want me to submit a MR on Gitorious), please let me know.

Thanks!
