Object-method Reform: - changed interface to object specific commands by requiring an   ensemble named "object". The rational behind is essentially   to use always the same info command to retrieve object   specific methods, no matter whether these are defined   on a plain object or an a class object (does not break   the "contract" what e.g. "info method" returns).

Now we define methods via:

  /cls/ method foo {args} {...body...}

  /cls/ object method foo {args} {...body...}

  /obj/ object method foo {args} {...body...}

Similarly, aliases, forwards and mixins are defined, e.g.

  /cls/ mixin add ...

  /cls/ object mixin add ...

  /obj/ object mixin add ...

  /obj/ require object method ...

The same change propagated as well to the "info" method.

Now we have:

  /cls/ info methods ...

  /cls/ info object methods ...

  /obj/ info object methods ...

Similar, the object parametererization uses

  /cls/ create obj -object-mixin M

  /cls/ create obj -object-filter f

  /metacls/ create cls -mixin M1 -object-mixin M2

  /metacls/ create cls -filter f1 -object-filter f2

- as a consequence,

 a) "/cls/ class method ...",

    "/cls/ class alias ...",

    "/cls/ class forward ...",

    "/cls/ class filter ...",

    "/cls/ class mixin ...",

    "/cls/ class info ..."

    "/obj/ class method require method ..."

    "/obj/ class method require public method ..."

    "/obj/ class method require protected method ..."

    "/obj/ class method require private method ..."

   were dropped

 b) "/obj/ method ....",

    "/obj/ alias ....",

    "/obj/ forward ...."

    "/obj/ filter ...."

    "/obj/ mixin ...."

    "/obj/ info method*"

    "/cls/ create obj -mixin M"

    "/cls/ create obj -filter f"

    "/obj/ method require method ..."

    "/obj/ method require public method ..."

    "/obj/ method require protected method ..."

    "/obj/ method require private method ..."

    were dropped

- added package nx::class to allow optionally the "class" notation

 "/cls/ class method ..." (and friends, see (a)), and

 "/cls/ class info ...

- added package nx::plain-object-method to allow optionally plain method

 b) "/obj/ method ...." (and friends, see (b))

- add support to slots to use ensemble methods as setters
