Upgrade guide: v1.5.0 -> v1.5.1-t

1. Be sure you have done the upstream migration steps, see https://github.com/exodus4d/pathfinder/releases/tag/v1.5.1
2. Update Code

1. Add remote: $ git remote add tralafiti https://github.com/tralafiti/pathfinder.git
2. Fetch remote information $ git fetch tralafiti
3. Checkout branch: $ git checkout -b master-t tralafiti/master

3. Adjust conf/pathfinder.ini:

VERSION                     =   v1.5.1-t

(you can always switch back to exodus4d's frontend by removing the '-t' from the version)
