string composition from form fields

[Kennric]

We need a method in formsender that can take an arbitrary list of fields, and compose their contents into a colon-delimited string to be included in the body of the email.

This list should be specified in the form itself, using a hidden field.

for example:

<input type=hidden name="fields_to_join" value="name,email,phone">

would result in a string being inserted into the body of the email:

<name>:<email>:<phone>

To be more specific, this is what we need in the email:

# date field is the unix date code
$username:$user_first:$user_last:$phone:$company:$date:$email:ibm-power:support
