Grizzled-python

- Merged pull request from github.com/cr33dog, which adds
`from __future__ import with_statement` imports to `setup.py` and
one unit test, to support older versions of Python.

---------------------------------------------------------------------------

* Added installation dependency on `enum` module.

---------------------------------------------------------------------------

* Changed `grizzled.net.ftp.parse` to support the FTP `MLST` command,
based on (largely unmodified) code contributed by Andrew Scheller
(*gcode /at/ loowis.durge.org*).
* Added `java` to the list of operating system types in `grizzled.os`,
for Jython.
* Changed `setup.py` to copy stuff to the `gh-pages` directory, via local
"gh" command.

---------------------------------------------------------------------------

* Added `grizzled.proxy.Forwarder`, a mixin that aids writing wrappers that
forward some, or all, unknown attributes to a wrapped object.
* Graduated to 1.0. It's been around long enough.
* Removed `setup.py` reliance on `ez_setup` module.
* Removed `grizzled.collections.namedtuple`.

---------------------------------------------------------------------------

* Fixed various incorrect docstrings.
* Added `grizzled.file.list_recursively()` function.
* Fixes for PyPI.

---------------------------------------------------------------------------

* Updated to latest `ez_setup.py`
* Fixed `grizzled.text.hexdump()` to honor `show_repeats=True` in all cases.

* Added `pidfile` argument to `grizzled.os.daemonize()`. `grizzled.os.spawnd()`
was passing a `pidfile` argument to `daemonize()`, but `daemonize()`
didn't support it.
