[development] Hello from another developer/Want to add some features

[Karoly Negyesi]

#attributes => array('readonly' => 'readonly') . Or you can intrdouce a  
#type => view_only which would expand any element to a hidden and a  
markup. None of these require any core change.

> * Support for datetime and time fields.

I thought we have #type => date now.

This is not my expertise. Forms are :)
