Stéphane Goetz aa5602a0fb Refactor the tree system
Each element of the tree now only has one parent, not a parent array.

- Creating an elements doesn't necessarily rely on an existing file
- Moving elements unregisters elements from the previous parent
- Moved some helpers to the builder instead of Entry
