Fixed test to work to work without too much initial requirements.
Updated test configuration
Fixed print command for Python 3
Fixed except command for Python 3
Modified for Python 3.3 compatibility

- "restkit" replaced by "requests".
- "oauth2" (i.e. a package for protocol OAuth 1) removed because it was
  practically unused, but can be replaced by "oauthlib" if alse more
  advanced auth is desirable.
- Adjusted code that can easily share the same code base for Python 2 / 3.
- Fixed some mixed tabs
Improved speed, multiple db auth, fixed package dependencies, siplified...

- Improved speed as was usual. Pool by use requests.Session class.
- Python 3.3 is supported from Django 1.4 to Django 1.7 (currently dev 1.7.a2).
- Removed support for Django 1.3, but not cleaned much obsoleted code now
- Removed httplib2 as a dependency on restkit. The package urllib3 is better
  for similar things. (dependency of "requests")
- "auth" module prepared for support of multiple SF databases, see "sf_alias" here.
Fixed deprecation warning during tests about logging filters.
Full support for Python 2.6+ and 3.3+ with one common codebase (without 2to3)
Full support for Python 2.6+ and 3.3+ with automatic 2to3 in setup.py

- All usual tests work (manage.py and tox), but the new runtest.py
  is still only a fake that helps to run setup.py.
Merge branch 'py3-2to3' into py3-common, so that 2to3 will be not used
Removed distribute_setup.py due to obsoletion.

"distribute" is obsoleted. The latest one is only a stub for use the new
"setuptools". The file "distribute_setup.py" also didn't work with any
Python 3 solution.
Fixed problem with import salesforce.testrunner.settings caused by __init__.py
Removed code for Django 1.3, except the incorrect code that must be explained and fixed first.
Modified tox to use less environments for the default test
Fixed inspectdb for use without option "--database=salesforce"
Merge branch 'fix_issue26_2' into HEAD
Added backward compatibility switch for networks without IPv6.

- Configurable by the setting "IPV4_ONLY".
Added retries of failed requests/connections

It is configurable by the variable salesforce.backend.MAX_RETRIES very early,
e.g. from the module your application models.py.
Removed obsoleted conditionals dependent on removed Django 1.3
Bugs that should be fixed (tests skipped currenty)
