add command for raw scripted editing

selectionwalk action beginsel endsel

  The command iterates over all cubes in all selections and executes
  "action" for each cube. The cubes of every selection are framed by
  executions of "beginsel" and "endsel". The action script is allowed
  to make changes to cube attributes, and if it does, an undo point is
  automatically added. "beginsel" and "endsel" are optional.

  While the scripts are executed, several aliases provide further info:

  sw_cursel
    Position and size of the current selection. Valid in all three
    scripts. Holds four integer values for x, y, xs, ys. See command
    "selection" for details.

  (all following aliases are only valid during the execution of the action
   script and provide the attributes of one cube of the map)

  sw_abs_x
  sw_abs_y
  sw_rel_x
  sw_rel_y
    Absolute and relative (within the current selection) coordinates of
    the current cube. Read-only values.

  sw_type
    Type of the current cube. Can be 0..4 for SOLID, CORNER, FHF, CHF and
    SPACE. May be changed to other numerical value or keyword.

  sw_floor
  sw_ceil
    Floor and ceiling heights of the current cube. Range -128..127

  sw_wtex
  sw_ftex
  sw_ctex
  sw_utex
    Texture slot indices for wall, floor, ceiling and upper wall of the
    current cube.

  sw_vdelta
  sw_tag
    Vdelta and tag values of current cube.

  sw_r
  sw_g
  sw_b
    Current light values of current cube. Can be edited, but only with
    temporary effect. Will be reset with the next light recalc.

The command is mostly useful for statistics scripts (like counting cubes
with certain attributes), but is can also be used for scripted editing,
as the following (useless) example shows:

  selectionwalk [ += sw_floor (rnd 2) ]

Further changes:

  The command listoptions now also can return the names of cube types:

    echo (listoptions cubetypes)

  The command countwalls is now implemented as a script instead of a
  builtin command. The script works better, because it doesn't create
  unnecessary undo points.
