Files app: - removed file list template, now rendering list from JSON response - FileList.addFile/addDir is now FileList.add() and takes a JS map with all required arguments instead of having a long number of function arguments - added unit tests for many FileList operations - fixed newfile.php, newfolder.php and rename.php to return the file's full JSON on success - removed obsolete/unused undo code - removed download_url / loading options, now using Files.getDownloadUrl() for that - server side now uses Helper::getFileInfo() to prepare file JSON response - previews are now client-side only Breadcrumbs are now JS only: - Added BreadCrumb class to handle breadcrumb rendering and events - Added unit test for BreadCrumb class - Moved all relevant JS functions to the BreadCrumb class Public page now uses ajax to load the file list: - Added Helper class in sharing app to make it easier to authenticate and retrieve the file's real path - Added ajax/list.php to retrieve the file list - Fixed FileActions and FileList to work with the ajax list Core: - Fixed file picker dialog to use the same list format as files app
