HTMLForm: Generate XHTML forms with Javascript validation

This class can be used to generate XHTML forms with Javascript to perform client side validation.

It can compose a form added all the types of basic HTML form inputs. It also provides convenience functions for adding input for specific purposes, like password and confirmation inputs and password change inputs.

There is a separate class to implement advanced text are inputs.

The class automatically generates the form HTML with Javascript code for browser side validation. It uses a table based layout, using HTML templates built in the class.

The class supports several types of validation based on regular expressions.

Server side validation is also possible with a separate script. That script also takes care of file uploading saving the files to a given directory, eventually generating thumbnails in the case of image file uploads.
