don't print filename on Creator()

[rgaudin]

I think it's a debug value that's no longer needed.

python-libzim/libzim/writer.py

Lines 138 to 139 in 2cdfa1c

	def __init__(self, filename, main_page, index_language, min_chunk_size):
	print(filename)

Do I just clone, attempt to fix, and make a pull request?
