updated models and preprocessing + bug fixes + more
there are now several models available and we can switch between them in the live command line via the new "load" command
also added "classify" command to rund the classifier against a given text
changed some preprocessing + added abbreviations matching. now we replace WTF or OMG
updated tests
added the tweets.csv file that was used for creating the models.
note that I removed the attributes "MENTION" and "URL" because they had way too much influence
