- fix usb using the wrong year when polling the timestamp. - fs file/dir has been re-written to allow for simplified calling and remove the need of manually closing. - add SetSize for stdio by using ftruncate. - don't truncate the file when opened in stdio. - add getcount api for stdio. - display file/dir count in filebrowser for non-native fs. - allow hash to be used on non-native fs. - slightly optimise nro parsing by manually calculating nro size rather than doing an os call. - slightly optimise nro parsing by keeping the fs struct alive between calls, rather than creating a new one on the stack. - fix filebrowser peeking into zip files that are stored on non-sd fs. - set the timestamp of a file moved to a stdio location (cut/paste). - slightly optimise daybreak update folder detection by skipping opening/polling the dir size. - set the fullpath of the file thats being hashed in progress box.
