chat macro for submitting arbitrary POST forms

Macro totes written by HeeHeeHee:
/goto '?'':function(){fetch(new Request('$1', { credentials:'include', method:'POST', body: new URLSearchParams('$2-&pwd='+pwdhash)}));throw{};}(); z='

Macro to, say, /post and you can do fun things like '/post choice.php whichchoice=1217&option=1&a=4341&b=4341', which handles the sweet synthesis choice adventure (assuming you've already gotten there with /cast sweet synthesis), or '/post inv_use.php whichitem=4474&checked=1' to fight a bricko ooze.
