adding recording webworkers to the dist copy
fixes #1738 new entry seems to not be blue
the input is somtimes empty now
fixes #1693 using FIeldDB equality function to detect if datum really  changed
maybe fixes #1332 commenetd out the uniqueing of usernames
exponential decay on fetch per datalist, not for all datalists (each datum in spreadsheet has a datalist on it now)
now that spreadsheet uses the corpus doc not just the dbname

we should probably use the variable name corpus instead of DB, and maybe this will help with the fielddb directives linking up to the corpus.
import directive is able to wait until the corpus doc is ready
found more DB that should be corpus
creating a datum field directive

for #1777
