Allow all textfield-sizes in schema, remove predefined length.

When defining the size of a text-element in the schema. The only allowed values are predefined fixed vlaues.
See CRM_Core_CodeGen_Specification
/**

• Sets the size property of a textfield.
• See constants defined in CRM_Utils_Type for possible values
  */
  protected function getSize($fieldXML) {}
  For example it's not possible to define a field size of 30 in the schema. (Even more when you do, it creates a size of 40 (the default value)).

My suggestion is to remove this limitation, and remove the double array mapper. I would alos remove the generated classes and corresponding css.
