Utf8-conversion without contents check as proposed by J. Templ. Refs: #19.
Docu for module Strings states explicitly that there are no contents checks in Utf-8 conversions.
Minor simplifications in StdLoader.
HostMenus.ReadCommandLine.CopyName uses module Strings for handling lower-/uppercase characters.
Kernel.LoaderHook parameter 'name' changed to 'utfName'.
