Moving all the work for war-creation to be done in a temporary directory
- Allows war to be created whilst BRJS is running
- It's wrong to create temp folders inside the apps dir (triggers off jsdoc placeholders etc when they're created and file-locks on Windows)
Ensuring that we use the same dir name (e.g. default-aspect instead of just 'default')
