Missing __version__ attribute

[rasbt]

Hi there,
I just noticed that missingno does not import the __version__ attribute properly, which causes the following problem:

>>> import missingno
>>> missingno.__version__

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-5-dc94dfc5cf5c> in <module>()
      1 import missingno
      2 
----> 3 missingno.__version__

AttributeError: module 'missingno' has no attribute '__version__'

Not sure how you think about it, but I think it would be useful to move the __version__ attribute to __init__ so that users can import and check the __version__ of the missingno package that they are currently using.

Should be (re)fixed now in the 0.3.4 release, cf. watermark#27, #19, my own clumsiness.

Wow, that was quick, thanks! :)
