Does not handle spaces in path correctly

[tempelmann]

If I rename "Downloader.app" into "Xcode Downloader.app", the space in the name leads to the download script to fail.

Clearly, the path of the app is used as the destination path, and somewhere in that script quotes are missing to ensure the spaces are not seen as a command argument separator.

Work-around: Use a "_" or "-" or something else instead of spaces when renaming the app, and anywhere in the parent folders where one might place the app.
