Creator is also released under this version of the GPL.

Necessary because the CppHoverHandler uses QtHelp and moved from
CppTools to CppEditor.

Lowercase is the more prevalent style in this plugin and CppTools.
Unfortunately CPPEditor can't be named CppEditor cause of the CppEditor
namespace.

It used to be in CppTools, but since the hover handler only makes sense
in the context of the C++ editor, this is a better place.

Doesn't seem to make any difference in performance, but doesn't make
much sense either.
