QDesktopServices documentation should mention QStandardPaths

Since the QDesktopServices::storageLocation() method has been removed, it doesn't appear anymore in the documentation page http://qt-project.org/doc/qt-5.0/qdesktopservices.html (it only appears in the "Compatibility members" section).
For developers porting their code from Qt4, it would be very helpful if the QDesktopServices documentation provided a very evident note stating that the storageLocation() and displayName() members have been deprecated and that their Qt5 equivalents are part of the QStandardPaths class.

Also, the StandardLocation enum should be part of the "Compatibility members" section, and not appear in the documentation of the QDesktopServices class.
