RMMV javascript tutorial #8 - handling of custom data

Disclaimer: Sorry for the sound quality, but I forgot to plug in my microphone, so it picked up my headphones. Made subtitles instead. Part 8 is now up! This time we'll talk about how to handle custom data, in other words how to load a custom database file and how to store custom variables. If you have any questions, comments or requests, feel free to leave them in the comments! Your requests might help shape the tutorials in the future.
