spacejam on Windows crashes during startup

[leosco]

Unfortunately, it looks like that age-old Mac to Windows issue where spaces in directory names are screwing up command execution.

spacejam: spawning meteor
[[[[[ Tests ]]]]]

=> Started proxy.
=> Started MongoDB.
spacejam: meteor mongodb is ready
spacejam: Warning: Error enumerating mongod children:
 'C:\Users\Leonidas' is not recognized as an internal or external command,
operable program or batch file.

spacejam: Warning: Enumerating mongod children returned with error code:  1

And phantomjs crashes further down:

=> Started your app.

=> App running at: http://localhost:4096/
spacejam: meteor is ready
spacejam: spawning phantomjs
   Type Control-C twice to stop.
