Revert r49558: [FIX] Jquery validation commonly added for antibots. Ref: http://dev.tiki.org/item5004
The {jq} smarty object does not inject the javascript in the page where the template is included, but adds it to the script block at the end of the page using headerlib, so all this commit does is add the antibot code to every page whether it's required or not.
Includes fix r51340 that corrected a simple javascript syntax error but the js can be further improved (coming soon...)

[FIX] captcha: A couple of very minor code improvements - antibot form validation seems to work fine now (is wish5004 still a problem?)
