add update system

• For games.csv the program will download the canonical games.csv from the raw github file once per day or every time it opens or whatever
• For the main program the github repository will contain a VERSION file that has the most recent program version. The client will check this on startup. If it is different to the one it has, the client will prompt the user to download the latest release from the releases section on github.

Problem: the updated release will be in the form of a .zip with all files. This will overwrite the games.csv the user has, potentially erasing any modifications the user has made, so some care must be made to come up with a system that avoids this problem, such as having a "canonical" games.csv hidden somewhere in some folder, and a games.csv in the main program directory that is initially a copy of the hidden version, that will remain when the program updates, and on program startup will have any new entries added from update to csv.

nevermind just use github api to download latest release zip, then use included 7z.exe to unzip into script directory.
