We should not rely solely on the provided size information.
Therefore the system needs to recalculate the size of each file in the zip file,
whether small or big.
The changes also cover the filemanager.js file if an error appears.
- Files that are references to external resources have special shortcut icon in filemanager
- When user selects a REF file in filemanager, he can see the 'Original' of the file in the way that original repository wants to show it, it is loaded dynamically via AJAX request
- Files that are themselves the source of references of other files in the system have 'link' icon in filemanager. When user tries to remove/rename/overwrite SRC file he is warned that all ## existing references will be updated/converted to copies.
- Changed confirmation messages for deleting, moving/renaming of the folders
- confirmation dialog in filemanager is using YUI3 now
- added new functions to the backend (repository/draftfiles_ajax.php) to allow changing of file name, location, license and author in one request
- enabled changing file properties using JS UI (lib/form/filemanager.js)
- when loading core_filepicker we extend the Node element with functions necessary to display files list in different view modes;
- repository/filepicker.js is changed to use those functions;
- FileManager now has three different view modes (icon view, tree view and table view), JS code is re-used from FilePicker;
- files in FileManager no longer have context menu, they have one popup Widget with different actions instead;
- Added more templates for JS code to FileManager, use similar CSS class names as FilePicker;
- lib/filelib.php : fixed double slashes in path, return more data about files;
- lib/form/filemanager.php : pass information to FileManager about available licenses and default author;
- repository/draftfiles_ajax.php : return information about directory tree for file moving UI in FileManager, return formatted information;
- repository/lib.php : function repository::prepare_listing() now can work also with draftarea files listing;
