Fixes #619.

copyAddonData used fs::create_directory (one level) on the destination and nothing for single files, so a project without bin/data yet (just src/ + addons.make) failed to get its addon data: Error creating directories ... No such file or directory / Can not add addon data file. Now create_directories on the destination folder (the folder itself for a directory, the parent for a file) before copying.

Tested an addon with ADDON_DATA = data/addon_shaders (folder), data/settings.json (file), data/deep/er/n.txt (nested file), into a project with only src/ + addons.make:

	linux64	osx	vs
master	nothing copied, errors	folder + file, nested file missing	nothing copied, errors
this PR	all 3	all 3	all 3

Combined into #683.
