Cannot build brackets with spaces in pathnames

[JeffryBooher]

The default git folders on Windows XP are located under C:\Documents and Settings\My Documents\GitHub\

The spaces in the paths cause the grunt script to choke on the unzip command
"Error: Command failed: unzip: cannot find either c:/documents or c:/documents.zip"

On Windows, the command processor will separate args sent to commands with a space or comma. The way around this is to quote the arguments with spaces or commas.

This could be a problem just by cloning into a folder name that has spaces in its name, however. This doesn't fail on Vista and later because the My Documents folder was changed to "C:\Users\Documents"

Not sure if this is a problem on Mac/Linux so marking Win Only for now
