Subject: [PATCH] Dont overwrite profile data (#2440)

This way a user can take multiple data samples from one/multiple play
sessions quickly. Creates a directory called profile_data that is added
to gitignore to place the data in, and checks to see if a file is there
and if so it creates prof1.json prof2.json prof3.json and so on...
