* Make tree-view work with CSS only
Changed the file list tree-view to use recursive templating instead of
an external function, and improved it so that it works with only CSS.
Striped lines won't work though.
* Remove inline-block from folder label
It breaks with the text-overflow: ellipsis.
* Rename makeFolderData to makeTreeViewData
* Add tree-view file list
* Add TotalSize field to folders
* Remove bootstrap/jquery related code
* Add icons to filelist, some CSS formatting
Moved a few styles from the format string for the tree view, to CSS
(where possible). Make icons look consistent under all themes.
* Make filelist hideable again, show it when JS is disabled
