Comparison operators such as =, !=, <, >, <=, >= should support a
one-arity version too, and return true in those cases (except for !=,
which returns false).
This closes#949.

This changes with syntax from (with [[x (expr)] (expr)] ...) to (with
[x (expr) (expr)] ...). Should have no ill side effects apart from the
syntax change.
Closes#852.

This changes let to use a flat list of symbol-value pairs instead of a
vector of vectors. One side effect is that (let [[a 1] z]) is not
expressible now, and one will explicitly need to set a nil value for z,
such as: (let [a 1 z nil]).
Closes#713.

apply now mangles strings and keywords according to the Hy mangling
rules (by using the same function, now imported from
hy.lex.parser). With this change, if the dict passed to apply has
keywords, strings or quoted symbols, they'll get mangled, to turn them
into proper keys.
This only works for the cases where the keys are directly in the apply
params. A previously deffed dict, or key through a variable will not be
mangled.
This closes#219.

To make it easier to write --init-- functions, defclass will now check
any (setv) expressions (and its property list), to find any --init--
declarations, and append a nil to the end.

On 21 September, all the continuous integration checks on a revision of
pull-request #920 were observed to fail with a "CoverageException:
Unrecognized option '[run] exclude_lines=' in config file
.coveragerc". One can only imagine that this was due to it trying to use
the new version 4.0 of Ned Batchelder's ever-popular coverage.py (just
released on 20 September), with which our existing .coveragerc would
seem to have not been compatible.
Re-indent `fib` examples to match that in original blog post - "Indentation shall be two spaces, except where matching the indentation of the previous line"
For easier macro writing purposes, allow an empty (cond), that simply
returns nil. Closes#904.
