Remove twitter-text dependency and related methods

This was causing more trouble than it was worth, mostly due to
twitter-text's hard $KCODE requirement.

Technically, removing methods should require a major version bump but
since these methods were just added in 2.0.0, I'm consciously breaking
the API. This may come back to bite me someday, but I can't think of a
better solution.

Users who want to continue to use these methods can extend the
Twitter::Status class.

 maintain over time. As a result, you can no longer build queries by chaining
 methods (ARel-style). The new syntax is more consistent and concise.
 
-Version 2 also includes some advanced Tweet-parsing methods, for example:
-
-    # Fetch the Tweet at https://twitter.com/twitter/statuses/76360760606986241
-    status = Twitter.status(76360760606986241)
-
-    # Return all hashtags in the Tweet
-    status.hashtags #=> ["Photos"]
-
-    # Return all URLs in the Tweet
-    status.urls #=> ["http://t.co/qbJx26r"]
-
-    # Return all users mentioned in the Tweet
-    status.user_mentions #=> []
-
-Tweet parsing is performed by [twitter-text][], Twitter's official text
-processing library, so it should be consistent with all other Twitter services.

 This version also introduces object equivalence, so objects that are logically
 equivalent are considered equal, even if they don't occupy the same address in
 memory, for example:
