LI tags now draggable
On drag, test if we are dragging with a key down. Also focuses CM editor
to show the cursor incase we want to drop into code and we'll then know
position
On drag end, perform a dropfile function
The branch DIV is now a temp DIV only and not seen. Previously it was
seen onload of ICEcoder as the display of the root. However, there were
inconsistencies in line returns etc and so now even the root has a
branch built for it on load. ie, the init load and branch generating use
the same system.
Set fmReady to true if not when finished animating the folder. This only
happens on load of course and means we run init afterwards
Test if we have a nextSibling before determining a tagName. This is so
if we have a dir with only subdirs (ie, no files) and the last subdir is
empty, there will be no UL list (which we're looking to maybe remove).
No longer need to consider depths as we are getting folder/file listings
for 1 branch at a time. For this reason, the opening UL will always be
block and the closing one shown when it's the last item and $GET
location is available (ie, not the root).
We don't want to have the DIV tag as part of the nest, so tuck the start
& end tags into the if $_GET location statements, so they only appear
with get-branch and never get injected into the tree
Instead of not showing perms span tags, show them with blank content
Due to format changes, we need to change the slice range to 28 and -7
