Added / Fixed some set codes
Change basically everything except for the set table - use a new CSV library, restructure convert.js to work with that.
clean up index.html and try some fixes for convert.js outside of the local page restrictions
Fun fact - if you actually call the parse function once there's a value in the input, it might work better. Also let's try worker thread since these CSV files are probably too big.
fix a bunch of sloppy errors, test on internet
It works! Now I need to contact decked/mtgo-stats to get the last few sets included :)
remove old library
