Python3 support

[itbabu]

I'm working on Python 3 support.
This pull request is not ready yet.

First I need to see how tests run with Travis (I wasn't able to run them on my fork) :)

Hey many thanks for this !

Can you explain why you switched to postgis for running tests ? ( just wondering )

If you need help for travis and multiple python versions, just ask, we could setup tox.

hi,
pysqlite seems to dislike Python3.

https://travis-ci.org/itbabu/django-leaflet/jobs/17015425

$ pip install git+git://github.com/tinio/pysqlite.git@extension-enabled#egg=pysqlite
Downloading/unpacking pysqlite from git+git://github.com/tinio/pysqlite.git@extension-enabled
  Cloning git://github.com/tinio/pysqlite.git (to extension-enabled) to /home/travis/virtualenv/python3.3/build/pysqlite
  Running setup.py egg_info for package pysqlite

        (result, consumed) = self._buffer_decode(data, self.errors, final)

    Complete output from command python setup.py egg_info:

I was able to pass the tests with python2.7 and Django1.6 / Django 1.5 (here)

But then later (here) Travis got a 503 from external services and it failed before running the tests.
I tried to re-run the tests today, but the 503 is still there.
I 've not yet seen that part of django-leaflet so I don't know what to do now.

Tests pass on Python3 too.
I still need to figure out what it is going on with Django 1.4

@leplatrem This should be ready for review.
I changed a bit the quicktest.py to allow tests with different databases.
The default test behavior is not changed.

python quicktest.py leaflet and the tests will be with sqlite (the--db is optional ).

python quicktest.py leaflet --db=postgres and the he tests will be with postgres.

Notes:
No tests with Django 1.4 and postgres.
No tests with Python 3 and sqlite.

Why switch to list ?

[itbabu]

self.apps is a list now so I cannot concatenate it to a tuple.

I like it very much ! Thank you !

This is amazing :) I wrote a couple of remarks, but those are details...
