Dependency instructions are overly complex

[samtstern]

In the README (and around the internet) the recommended way to include the twitter library is this:

compile('com.twitter.sdk.android:twitter:3.2.0@aar') {
    transitive = true
}

As far as I am aware, this is completely equivalent to this:

compile 'com.twitter.sdk.android:twitter:3.2.0'

Android gradle infers the @aar and transitive is true by default.
