/*** Generic validation function, this should be correct to validate any type of form ***/
/*** Introduction: All field names specified of fields you want to validate in form should start with validation type tag, + and 
then field you want to give to a field. In example, if you want to validate that a field is not empty and it is a email, 
field name should be: re+email (r for required, and e for email). If you want to show errors using innerHtml I suggest you to
id content boxes with same name as fields validated plus '_error' or something similar, so you should only change 'alert()' 
functions for document.getElementById('name_error').innerHtml ***/
