interp 6c99e3a707 Remove image button bug (thanks to Eric Knauel for reporting this): Image 
buttons return the coordinates where the user clicked à la
imgbtn321.x=13&imgbtn321.y=12. Thus, we cannot search for the
input-field-name of the image button. To remove this bug, we introduce
following changes:

surflet-input-fields.scm:

+ make-image-button returns a multi-input-field that searches for its
  coordinates in the bindings, returning a pair (x y) of it (numbers).
+ Adapt select-input-fields to interface changes of multi-input-fields:
  transformers get also their input-fields.

returned-via.scm:
Don't simply check for the input field name in the binding. Use
input-field-value to check for existance of the input field in the
bindings

input-fields.scm:
multi-input-fields get also their input-field as argument

web-server/root/surflets/byte-input.scm:
Adapt to interface change of multi-input-fields: transformers get also
their input-field

web-server/root/surflets/test.scm:
Check the image-button feature  correctly.

interp aa6e6aabfc ! Redesign of input-fields. 
+ Split input-fields into two structures:
  + surflets/my-input-fields allows you to create your own input-fields.
    (complete with structure surflets/input-field-value)
  + surflets/surflet-input-fields are the proposals for input-fields
    from SUrflets. They support annotated input-fields where
    appropriate (select, radio, checkbox, hidden) and changing of attributes,
    e.g. default values. See test.scm for examples.
  The interface of the structure SURFLETS has only changed slightly
  concerning the input fields
  (make-higher-input-field --> make-multi-input-field should be the
  main change)
+ Adapt examples to new input-field interface
+ Note new structures in documentation.

interp c48f952cc5 + Add annotated callbacks. 
Callbacks may now be annotated with arbitrary arguments with which the
function will be called. See surflets/test.scm for a (non-didactic) example.

* The extended callbacks justify an extra structure for callbacks:
surflets/callbacks
