[New feature]: label box can rotate by using short cut 'x' or 'c', but only support rotate one box at the same time

FIXED: process rotateImgAction after autoRecognition without any click on file list will raise A ERROR : array out of index

New functions: Open the dataset folder, image rotation, add shortcut key description, repair the direction shortcut key movement function under batch processing 

Spelling mistake, detection box missing,etc.
