Load blacklisted users & words from config file

[rajat404]

Changes are made to get the blacklisted users & words from config file. Also noting that the terms: "RT" and u"♺", are needed to be blacklisted regardless, they are separately added to the list wordBlacklist in the retweet.py file.

Hi rajat404,

could you use the split function instead of evaluating the config string with ast.literal_eval?

Please put your patch in one logical commit and I'll happily merge it.

Thanks.

I added the following lines after the search query to read the list of blocked users from twitter:

# get list of blocked users
for user in tweepy.Cursor(api.blocks).items():
	`userBlacklist.append(user.screen_name)```

Just don't know how to do the same with the blacklisted words.
