Review request for kdelibs.


Changes
-------

I'm now using KMimeType::extractKnownExtension as the set filter is not necessarily a MimeType filter (can be also just *.cpp etc.)
And if the KFileWidget is used with an uncommon filter which is not a known MimeType, I fall back to get the last part of the filename after
the dot as with my first patch.


Description
-------

In trying to fix mentioned bug, I found out the original problem lies in KFileWidget:
If I'm editing a JPEG file which has the non-mainExtension ".jpg" and KFileWidget was told to auto-select an extension,
then it did not check if the already given extension is one which is also allowed and simply removed
".jpg" and added ".jpeg", which is not what a user would expect.

This patch now checks the current extension against all allowed extensions and if there's a match, it
keeps the current extension. Only otherwise will it add the default extension.


This addresses bug 229547.
