Don't reload root on click & put things on 1 line
Only do DIV if location, tweak perms & slice fix

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
