Title: Prepare for Python3 compatibility

Hi,

In this commit, you'll find all the stuffs I had to do to be compliant at the same time with the C Python 3 API and the C Python 2 API, but without using a "#if PY_MAJOR_VERSION == 3" hack. This means:
- Add parenthesis to Python code (test and Makefile.PL)
- Change mixed space/tab in Python code with spaces only
- Remove DL_EXPORT/DL_IMPORT Macro (deprecated since Py2.3)
- Use Macro Py_TYPE, Py_REFCNT and PyVarObject_HEAD_INIT. Add "ifndef" since Python 2.5 does not recognize them.
- Add __dir__ method to perl package and perl object (`dir` is no more looking for `__methods` attribute in Py3)

In addition, few Py_DECREF/Py_XDECREF was missing.

Tested on Ubuntu 14.04 with Python 2.5.6, 2.6.9 and 2.7.6
