New Block : Contact Form

Part of the code is explained on
http://parsimonycms.blogspot.fr/2013/01/creer-un-nouveau-bloc-exemple.html
[FRENCH]

Feel free to modified it in anyway.

This block is derived from Form Add.

It makes an customisable contact form predesigned.
* When the contact form is filled, it sends an mail ,to the mail
specified in the Configuration, with the fields filled by the user.
* I tested it with the main fields (wyiswyg,state,textarea,string,email).
* You can configured an recaptcha to prevent spam directly from the
Configuration interface.
* Notifications are predesigned and captcha error are notified.

Known Bugs:
--------------
If Recaptcha is active without a public/private key or a wrong
public/private key it will broke the admin page.
You can repair it by modifying the block at
/profiles/www/modules/core/views/NAMEOFTHEBLOCK.php

Possibles Improvements
----------------
* Send an confirmation to the user.
* Make the State field value, the actual value not the numeric one. (ex:
thisisthefirstvalue instead of 1) on the email
* Notification deactivation
* Notify multiple email.
* Translation
* Prettier notification email
* Last forms responded sended at a defined period instead of every
responded forms.
* Captcha Alternative
* Captcha active after N tries.
