How would I add support for directories whose names have spaces in them?

@stevepiercy I just fixed that by adding quotes around the stored directory paths as well as around the path passed to the cd command. not sure if both are necessary but it works now!

Thank you for the fast fix! That did the trick.

Nice, Zach. I could definitely use this to switch back and forth between project contexts.
