Fix multiple inputs in one label: it's invalid ��

Multiple inputs within a single label in invalid HTML. This bug can not
only occur in multi-fields but also in plugin-provided single fields
which may contain multiple input-fields which are then only combined by
javascript.

Thus, we provide an id which every type can assign to the edit-field
best suited. For multi-types this is usually the new-input-template.

Always use raw values for editors

This is another attempt to fix #140. The valueEditor() and
multiValueEditor() now always expect raw values to be passed. The Value
class was adjusted accordingly. It now allows to set the raw value
(which is what we get from POST). If done, the Value object is treated
as a rawonly Value that will throw an exception when you try to access
value or displayvalue.
