Removed ZendRest as requirement

- ZendRest only worked with XML; v1.1 of twitter api is json only
Added develop branch as alias
Spring cleaning

- s/Akismet/Twitter/
Refactored Twitter client to v1.1

- Use JSON, which means remove usage of REST client, addition of Response
  object, and renaming of "local" http client
- Replace XML response payload stubs with JSON responses
- Remove methods no longer available
- Ensure parameters are correct for exposed methods
Fixed failing/errored tests that used stubs

- Removed obsolete endpoints
- Removed tests for the above
- Fixed a few tests to refer to appropriate methods
All TwitterTest test cases now pass

- added screen name validation where necessary
- removed "statuses/:id/retweeted_by", as endpoint no longer exists
Verified all endpoint parameters against API documentation
Added TODO list of methods yet to implement
Normalize dynamic method/property names

- Basically, allow notation as described in API: direct_messages,
  mentions_timeline, etc. __get() and __call() now remove the underscore
  and lowercase the argument before attempting to validate.
Alphabetized API method calls

- Makes it simpler to determine where new ones should be added
Added search/tweets and users/search
Search, OAuth, and HTTP Client

- Wrote tests for search
- Figured out a better way to configure both the OAuth support and HTTP
  client. You can now do the following:

  $twitter = new Twitter(array(
      'access_token' => array(
          'token'  => 'your-access-token-here',
          'secret' => 'your-access-token-secret-here',
      ),
      'oauth_options' => array(
          'consumerKey'  => 'your-consumer-key-here',
          'consumerSecret' => 'your-consumer-secret-here',
      ),
      'http_client_options' => array(
          'adapter' => 'Zend\Http\Client\Adapter\Curl',
      ),
  ));
Removed old Search class

- Not necessary; all search is now done via 1.1 API
Added tests for users/search
CS fixes

- trailing whitespace and EOL characters
- updated TODO to remove search/tweets and users/search
Added docblocks to Response object
Rate limit status changed namespaces

- Now in "application" namespace instead of "account"
