Proposed cleanup of code base for QMAKE_COPY_DIR (dead code ).
As of qt5.9(ish), which includes all the current stable distro releases, the directive QMAKE_COPY_DIR has been (essentially) a noop if one does not have explicit [group] commands to utilize them (although they are still carried forward in various created Makefiles just in case). So the attempt to call cpsvndir and cpsimple have not done what they might have done (or were intended to do) in the past. This is dead code.
As background, the cpsvndir and cpsimple scripts essentially performed a recursive copy, and then removed any .svn directories, but .svn directories have not existed for, well, quite some time, in the code base. In addition, cpsvndir modified python file shebangs according to any specified python in configure. But, as it is no longer called, it does not perform that work, and in any case, there is a pending python3 pull request that will modify the python requirements in different mechanisms. And for the themes and html directories there are no python files that currently need adjustment in any case. All dead code now.
Patches attached (individual patches so that they may be more easily reviewed by a developer)
