Modify template path lookup order and fix bugs:

  - [x] Modify template path lookup
    - [x] Path lookup occurs in the following order: Home, pwd
          Modify to look at specified dir (`-d`), then pwd, then user home
  - [x] Add Ansible playbook `defaults` dir
    - [x] Fix bug in `FlightControls.Checkbuild()` where it is checking for
          ansible files when it shouldn't as `requiredFiles` is actually
          passed in. => used `requiredFiles`
    - [x] Add Trace calls to see files being found
