Modify label.py to handle multiple people performing the labeling

@skulltech Yes! I am on it.

@marco-c Is it necessary to have different files for different persons? Like one person starts labeling images and has labeled 100 of them and then leaves, then we will create a file with these labels. Next day he again starts but the file name is not saved so he will have to start from start. Should I add a name_text_box in the start so that person is able to enter the name or select the file from drop down menu if he wants to append results to it?

The person should be able to specify who they are by passing a "--person" option to label.py. The files will be named "labels_PERSON.csv", so they will be able to append results to it.
