adds zero-width-joiner input method

[rokke-git]

adds completion method for combining characters, and an easier way to
input sequences of emoji. this also fixes the help-text for a wide range
of emoji, such as "👨‍👩‍👧‍👦" and "👨‍💼".

spawned from this discourse topic

idk exactly how the tests are meant to work so I just copied from the koala test

edit: oops, the length is actually the number of completions, not the number of chars in the completion. should be passing now

I saw an opportunity for adding a nice latex-string lookup, what do you think of it? since \: is emoji, doing \? for reverse-searching makes sense; like how we have ] for pkg and ? for help. output looks like this on my computer:
