use more efficient search for emoji.gs

[faretek1]

It would be more efficient to use alphabetical lists for the large lists in emoji.gs (possibly leading to 2 sets of 2 lists) so that you can use a binary search, because scratch '<' operator works with alphabetical (unicode index) order

the existing emoji list might already be in order of emoji, but there is no set that uses a sort of emoji names

goboscript repository has the js script that generated the emoji.gs file

dealing with comparions between strings in scratch is an annoying nuanced thing because scratch converts strings to lowercase before they are compared. this means that simple binary search simply does not work. If it's emoji-only (and not full unicode), this is feasible, but it would need to be benchmarked against the builtin item in list block
