Similar functionality to _post.

It is good for many things as it can help the tree be more readable:

  • resetting or making sure a variable exists
  • updating status to know a node has started.

66fb139 
Add a new precondition type _onStart that allows executing scripts
before a node starts its tick. This provides symmetry with the
existing _post functionality.
