- Reading readonly properties

- Added system for readonlys: Readonly is passed in constructor as third parameter. If a widget class is registerd with "[type]_ro" (see et2_textbox for example) this one is created
- Added new 'valueWidget' base class which introduces the 'value' attribute and implements auto loading from the content array
- Implemented readonly attribute for buttons and textboxes
