Configuration of FormHandler.

There are 3 different levels of configuration. This is easier than it
sounds.

1. Script configuration 
First you can configure the script for every form that uses it. This is
done in the configfile.inc.php. Look at the options and change what is
necessary (the documentation is in the comments). NOTE: Be REALLY carefull
with the last lines of configfile.inc.php. If you change them, you probably
have to change the php-code in the defined modules. Let this be a warning.

When you have done that, the script is ready for use. Now create a form
(see the example email.html) and let it use your version of the script. For
more information on building HTML-forms look in your/any online HTML
tutorial.

2. Form configuration
In the HTML-form you find the second level of configuring. These are the
per-form options only used in this form.

3. Configration file
When you don't want any configuration options in your form or you want to
have some configurations for more than one form, use the configfile option
in the form:
<input type=hidden name=configfile value=myconfig.txt>

This will load in all the options from config/myconfig.txt. This file
(still) needs to be in the configured subdirectory near the script. Remote
configuration is not possible (yet).

You can create different configfiles for every form or create one
configfile for all forms to set some default values.

The options that can be used in the form and the configfiles are documented
per module in the docs/ directory.

WATCH OUT: there are two options that may be confuse you:
- configfile: to load options from a configuration file (see 3.)
- config_file: to replace the overall configurationfile
	(configfile.inc.php)

Be very carefull with building your own configfile.inc.php. This is very
hard to do, because it sets the order in which modules are loaded. When you
edit there is a good (bad) possibility the script isn't working anymore.
Only do this when you have looked really carefully to the code. Don't say I
didn't warn you.
