QFileDialog: Manually typing a filter into the file name field does not sort the files as a filter should.

When manually applying a filter (e.g. *.h) in the file name field of QFileDialog, the first file with that extension is selected.

The user would expect that the files they view are filtered to only show the files they are filtering for.

If a user chooses not to use the static QFileDialog calls, then the behavior should still be similar to the native one.

At present, it is not much like native at all.

Update:
The static QFileDialog functions use the native file dialog. This is a different dialog than the Qt implementation, which is cross-platform, with different behavior.
This has been changed to a suggestion for more windows-like behavior in the Qt file dialog.
