TreeList updates for the outliner sidebar

Browse Source 
All data items now get their `item.treeList` api added even if deferBuild is set.
This means the apis can be used regardless of whether the tree has built their
ui pieces.

Also adds a number of new api calls

Top-level methods:

 - clearSelection - clears selection from the list
 - filter(filterFunc) - filters the tree using the provided function

Data item functions:

 - item.treeList.sortChildren(sortFunction)
 - item.treeList.replaceElement(element)
