Validate_fields Class

A small improvement in the create_msg() method
makes it possible to switch between the XHTML
version and the simple HTML version. In the fields
array one key was named "name", and it has been
renamed to "value" to make it more clear. The
variable declarations at the beginning of the
validation method was removed. Because the value
of a checkbox (radio) type field is only available
if the element is checked, there are new functions
to validate this elements.

The regular expression pattern of the check for
HTML code wasn't good, but is working now. The
example page was modified to test general text
inside a textarea (which is useful to test the
HTML code check). There are also Spanish
translations for the messages now.

A small bug inside the email pattern was fixed.
Danish translations were added.

The validation of email addresses was not good. The regex pattern has been changed to validate the most common cases.

Negative integers will now be validated. A new
validation method was added, called
check_html_tags(). If the $check_4html variable is
set to true, all fields will be validated for HTML
tags. The method for the URL check was optimized
and otherwise modified. It is now possible to
validate (nearly) all kind of URLs from the HTTP
protocol.
