Summary: Allow choice of copy function in shutil.copytree

Initial Comment:
It would be nice to be able to choose which of the copy
functions is used in copytree.  I am currently working
on a project where I would like to copy a tree, but I
do not want to preserve permissions so I'd like
copytree to use copyfile instead of copy2.

Here is a snippet of copytree from shutil.py that I
modified by adding a func parameter and defaulting it
to copy2.

def copytree(src, dst, symlinks=False, func=copy2):
.
.
.
        try:
            if symlinks and os.path.islink(srcname):
                linkto = os.readlink(srcname)
                os.symlink(linkto, dstname)
            elif os.path.isdir(srcname):
                copytree(srcname, dstname, symlinks)
            else:
                func(srcname, dstname)
.
.
.

I guess I should have tested it first.  I forgot to add the
func parameter to the copytree call within copytree.

Something like this:

.try:
.    if symlinks and os.path.islink(srcname):
.        linkto = os.readlink(srcname)
.        os.symlink(linkto, dstname)
.    elif os.path.isdir(srcname):
.        copytree(srcname, dstname, symlinks, func)
.    else:
.        func(srcname, dstname)
