+- Drop some not unnecessary library runtime Requires: libQt5Designer5,
+  libQt5DesignerComponents5, libQt5Help5, pulled in automatically.
+- Change libqt5-qttools and libqt5-qttools-doc Requires in devel
+  subpackage to Recommends, as the tools are not required for building.
+- Make some Summaries and Descriptions more useful.
+- Correct requires for matching Clang headers, the headers are part
+  of the libclang package for current Clang versions
