The core uses the "txt" and "chk" prefixes to know what to display and
how to handle the value of the cookie.
<<option txtCookieName>> creates a text input field, and the cookie
value can be any text
<<option chkCookieName>> creates a checkbox, and the cookie value is a
'boolean' (i.e., true or false)
Also, [[UploadPlugin]] adds support for password-input fields, which
work like regular input fields, except they show **** instead of the
actual text. This plugin-defined feature uses the prefix "pas", as
in:
<<option pasCookieName>>
