Wrap "Project Directory" lines to fix dir/ls for paths with spaces

[lkkuma]

A very small commit to fix this one little tiny detail that's been bugging me and I imagine has been bugging many others too.

Changes

• Wrap $UNITY_PROJECT_PATH in quotes on lines 54 and 126 to properly DIR/LS paths with spaces respectively
