Release v1.0.0-alpha.5 of zuQA

TL; DR - Bug fixes & performance improvements
-
zuQA generated nodes for flow-testing editor layout (attached image), these nodes got generated at runtime according to user's API collections. They were being written inside electron's apps bundle, causing issues in linux (cannot write in readonly package).

Fixed issue by using electron's user-dir for the same and packaged required utility code into a npm package which gets installed when app boots up.
