Title: Use CFBundleName instead of CFBundleExecutable for bundle name

If available, use CFBundleName instead of CFBundleExecutable for the bundle name.

I've used this approach myself to package inkscape.
It needs an executable in Contents/MacOS/inkscape in lowercase, whereas the rest of the interface should use a capitalized Inkscape.
