Add two new formats to jfmt/jval/jnamval -F

[xexyl]

The formats are '1line' for output JSON on one line with one space per token and 'nows' for 'no whitespace'. There might or might not be some kind of joke in here but that's to be determined by 'users of the source' ... assuming that there is one, of course :-)
