This library has a dependency on ps-tree, which has a dependency on event-stream which had a security bug in newer versions.
Hence locked ps-tree's version to 1.1.1 which uses event-stream's secure version 3.3.4

indexzero/ps-tree#33
dominictarr/event-stream#116

Changed local binary paths to support LocalBinary 7.3.
Fixed folder argument when building browserstack local arguments.
