Update Django version

[odyssey4me]

It'd be ideal to be able to make use of the more recent versions of DJango. I don't know how easy it will be to merge the updates in?

I made a new branch (django1.5) with an updated django. Everything appears to be working, but if you could check it out and make sure it meets your needs, I would appreciate it. I'll merge when I hear back, assuming all is well.

When trying to use curl to change the 'local boot' checkbox, the following error occurrs:

Piston/0.2.3rc1 (Django 1.5.5) crash report:

Traceback (most recent call last):

  File "/opt/djeep/.kick-venv/src/django-piston/piston/handler.py", line 134, in update
    return rc.ALL_OK

  File "/opt/djeep/.kick-venv/src/django-piston/piston/utils.py", line 55, in __getattr__
    class HttpResponseWrapper(HttpResponse):

  File "/opt/djeep/.kick-venv/src/django-piston/piston/utils.py", line 82, in HttpResponseWrapper
    content = property(HttpResponse._get_content, _set_content)

AttributeError: type object 'HttpResponse' has no attribute '_get_content'

This appears to be a well known issue: http://stackoverflow.com/questions/16294518/httpresponse-has-no-attribute-get-content

And there are some forks to deal with it, for example: https://bitbucket.org/spookylukey/django-piston

After trying one or two django-piston forks, I've verified that the above-mentioned fork works.

I've included the fix in #34
