[Bug] import elephant rendered useless by removal of imports in __init__.py

@dizcza said

Now fim.so is downloaded at pip install and during the import (mostly to support travis tests).
To do so, I merged version_file branch because it includes removing unnecessary imports at elephant/__init__.py

This removal of all imports from __init__.py means that import elephant does nothing.

In [1]: import elephant

In [2]: dir(elephant)
Out[2]:
['__builtins__',
 '__cached__',
 '__doc__',
 '__file__',
 '__loader__',
 '__name__',
 '__package__',
 '__path__',
 '__spec__',
 '__version__',
 '_get_version']

In order to use elephant, the user now has to manually import every subpackage they need by name. This breaks all code that uses import elephant! 👎👎

Indeed, as you pointed out, dir(elephant) should contain useful internal packages. I'll revert the change back soon.
