Now working with branch loading!

Only include settings file if we don't have ICEcoder settings available
Need 4 x vars for fileCounts etc available here
Contain tree within DIV which we can get the innerHTML of later for
branch injection
Need .$location when determining if a dir or not and also as part of the
path
If it's a folder and we have a treeType of branch or branchReload, add
true as the 2nd param, false otherwise
If we have a location, we're branch injecting, so get the target DOM
elem, create a new UL, set the style of it, remove whatever UL may be
there before, take the DIV innerHTML with the UL and /UL tags chopped
off, make it the innerHTML of our UL and finally inject into the DOM at
the right position.
4 x vars moved to get-tree.php

Need to make use of these for branch injection too
openCloseDir changes onClick & gets dir branch

Change onclick event by setting 2nd param to false so it doesn't reload
Broke setting of node.nextSibling down into 2 new items, may revise this
If we're due to load, pass that through to get-tree.php in the
fileControl iFrame to begin the process
