[Mobile] Hide Tree

On selecting a node in the tree, if the
user is on phone and in portrait, than
emit up to the browse controller to call
treeSlide(), which will hide the tree menu.
Also adjusted the agent service to properly
check for orientation using window.innerHeight/
Width. Also created function for the selection
of an object in BrowseController.
