FairGame 0.6.3 Hotfix

• Adding validation to min/max price and improved logging when an offer price falls outside the reserve (many questions pop up on Discord concerning this type of silent failure).
• Changed the log-level of several error conditions to warning/error instead of info.
• Added window-size option for headless operation. The default might make for unusable screenshots
• Updated .gitignore to ignore all .json files in config and the tags file for ctags users
• Improved tracking of the check/cart time
• Changed crash report to only trigger for unhandled exceptions and allow for error-free return on success or on ctrl-c
• Implemented buy box check
• change default pipenv install to store virtual environment with FairGame folder
