Extract attachments from emails that Gmail doesn't allow you to download. This is dumb. (Only tested with Python 3.4)

extract-attachments.py

# Get your files that Gmail block. Warning message:
# "Anti-virus warning - 1 attachment contains a virus or blocked file. Downloading this attachment is disabled."
# Based on: http://spapas.github.io/2014/10/23/retrieve-gmail-blocked-attachments/
# Go to your emails, click the arrow button in the top right, "Show original", save to the same directory as this script.
