Update tumblrdottext to work with api v 1.1

Needs:

[twitter]
oauth_token = 
oauth_secret = 
consumer_key = 
consumer_secret = 

In the config.ini. The tokens can be made at https://dev.twitter.com/apps (make a new app, give it some descriptive info, go to the "oauth tool" tab for your app). The oauth stuff is "access token" and "access token secret", and will need to be generated, but the consumer key and secret should already exist.
