jcrocholl/pep8 (used by flake8, used in Hy's continuous integration
builds) introduced an imports-at-top-of-file check in 1.6.0 and a
line-breaks-around-binary-operators check in 1.6.2. This commit makes
nonfunctional changes to bring the Hy codebase in compliance with this
tool, fixing #764.
Previously, Hy scripts that raised a subclass of IOError would be caught
by code intended to deal with IOErrors raised when Hy couldn't import
the script itself, resulting in either a misleading "Can't open file"
error message, or a misleading TypeError traceback from not being able
to format the "Can't open file" message (for IOErrors for which the
errno attribute was None). This commit (a straightforward implementation
of the idea proposed by @slimetree in #714) introduces a new HyIOError
class, raises that when `import_file_to_hst` can't open the file path,
and catches it in the `cmdline_handler`.
This is believed to fix#513, #714, and #727.
This code is heavily, *heavily* based off of Guillermo Vaya
(willyfrog)'s work... instead of defining its own keyword arg though, it
uses the "standard" :kwarg type, which is the main difference from
willyfrog's original branch.
Included tests and some documentation in the tutorial.
Also documented "apply" separately as an example of reproducing
*args and **kwargs.
When (fn) or (defn) does not get an arglist as first/second parameter,
emit a more descriptive error message, rather than an ugly traceback.
Fixes#716.

Our MetaImporter was being inserted at the end of sys.meta_path.
For Python prior to 3.3, this was fine since sys.meta_path
was empty by default. As of the completion of PEP 302 in Py3.3 and
later, there are several importers registered by default. One of
these was trying (and failing) to import simple Hy modules,
resulting in a failure to import anything inside __init__.hy.
This change simply inserts the Hy-specific importer at the front
of the list.
This was noted in issue #620 (great catch @algernon)
