* Returns html for displaying one file manager

* class="filemanager fm-loading";
* After all necessary code on the page (both html and javascript) is loaded,
* the class fm-loading will be removed and added class fm-loaded;
* The main element (class=filemanager) will be assigned the following classes:
* 'fm-maxfiles' - when filemanager has maximum allowed number of files;
* 'fm-nofiles' - when filemanager has no files at all (although there might be folders);
* 'fm-noitems' - when current view (folder) has no items - neither files nor folders;
* 'fm-updating' - when current view is being updated (usually means that loading icon is to be displayed);
* 'fm-nomkdir' - when 'Make folder' action is unavailable (empty($fm->options->subdirs) == true)
*
* Element with class 'filemanager-container' will be holding evens for dnd upload (dragover, etc.).
* It will have class:
* 'dndupload-ready' - when a file is being dragged over the browser
* 'dndupload-over' - when file is being dragged over this filepicker (additional to 'dndupload-ready')
* 'dndupload-uploading' - during the upload process (note that after dnd upload process is
* over, the file manager will refresh the files list and therefore will have for a while class
* fm-updating. Both waiting processes should look similar so the images don't jump for user)
*
* If browser supports Drag-and-drop, the body element will have class 'dndsupported',
* otherwise - 'dndnotsupported';
*
* Element with class 'fm-filelist' will be populated with files list;
* Element with class 'fm-breadcrumb' will be populated with the path or have class 'fm-empty' when empty;
* Element with class 'fm-btn-add' will hold onclick event for adding a file (opening filepicker);
* Element with class 'fm-btn-mkdir' will hold onclick event for adding new folder;
* Element with class 'fm-btn-download' will hold onclick event for download action;
