defclass reimagined
defclass now has a new syntax:

 (defclass Name [BaseList]
   [property value
    property value] ;; optional

   (defn method [self]
     self.property))

Anything after the optional property list (which will be translated to a
setv within the class context) will be added to the class body. This
allows one to have side effects and complex expressions within the class
definition.

As a side effect, defining methods is much more friendly now!

Closes #850.

contrib.walk: Coerce non-list iterables into list form
Expressions can sometimes contain itertools.islice objects, which we can
only walk if we force them into a list. To do this, the walk function
has to be taught that collections that are not instances of list should
be forced into a list.

c2982a9ae3 anaphoric: fix first & last when conditions fail
* hy/contrib/anaphoric.hy: `ap-first` and `ap-last` now handle cases
  when failure happens for the predicate. Thanks to @tutorto for
  reporting this bug

fa24042cb0 hy.contrib.walk: Add (macroexpand-all)
This function will recursively perform all possible macroexpansions in
the supplied form. Unfortunately, it also traverses into quasiquoted
parts, where it shouldn't, but it is a useful estimation of macro
expansion anyway.

817b4688d8 hy.contrib.walk: New contrib module for walking the Hy AST
The hy.contrib.walk module provides a few functions to walk the Hy AST,
and potentially transform it along the way. The main entry point
is (walk), which takes two functions and a form as arguments, and
applies the first (inner) function to each element of the form, building
up a data structure of the same type as the original. Then applies outer
(the second function) to the result.

Two convenience functions are provided: (postwalk) and (prewalk), which
do a depth-first, post/pre-order traversal of the form.

c69c14cc7d contrib/anaphoric: More anaphoric macros added
* hy/contrib/anaphoric.hy: The following anaphoric macros have been
  added
  `ap-reject` : Opposite of ap-filter, yields the elements when a `pred`
  evaluates to false
  `ap-dotimes` : Execute body forms (possibly for side-effects) n times
  with `it` bound from 0 to n-1
  `ap-first` : return the first element that passes predicate
  `ap-last`  : return the last element that passes predicate
  `ap-reduce`: anaphoric form of reduce that allows `acc` and `it` to
  create a function that is applied over the list

* docs/contrib/anaphoric.rst: updated docs to reflect these changes

* tests/__init__.py: updated to explicitly include tests for anaphoric
  macros
