Subject: site: use errormsg function for general survey errors

the previous commit introduced handling error messages using a
"setErrormsg" function. This is now also used for the general error
messages which may show up at the bottom of surveys.

However, since js and async things are weird, the code there is still a
long repetitive mess which can't really be cut down further.
