Fix for IMDB data processing + other minor changes

[RileyXX]

• Fix for IMDB data processing for versions 1.8.7 and below as mentioned in: https://github.com/RileyXX/IMDB-Trakt-Syncer/issues/88.
• Added version checker which prompts the user when running the script if a new update is available.
• Script now prints out the directory where the user's credentials and log files are located. This will make it easier for the user to make any necessary changes. As mentioned in: https://github.com/RileyXX/IMDB-Trakt-Syncer/issues/87.
