* Removes manual selectionModel update from controls-uit/Tree.qml
* This was interfering with the Key+Click functionality. It
was introduced via Commit 99617600c4 to address a selection
issue; however, it's unclear what that issue was. Selection
within the Asset Browser works without it at present.
* Amends the ContextMenu within the AssetBrowser to work in conjunction
with the multi-selection changes.
* ContextMenu will _only_ display when triggered within the current
selection be it one or more items as opposed to previous behavior
of selecting the item the menu was triggered on.
* CopyURL is only enabled when the selection size is 1
* Rename is only enabled when the selection size is 1
* Delete is enabled when the selection size is greater than 0
