title: Android theme error when adding a new dependency
body: <p>I'm following the examples on this sample from <a href="https://github.com/boxme/SquareCamera/blob/master/README.md" rel="nofollow">github</a> but when i add the dependency I recieve the error</p>
  
  <blockquote>
    <p>"
    Error:Execution failed for task ':app:processDebugManifest'.
    Manifest merger failed : Attribute application@theme value=(@style/AppTheme) from AndroidManifest.xml:20:9-40
        is also present at [com.github.boxme:squarecamera:1.0.3] AndroidManifest.xml:11:18-76 value=(@style/squarecamera__CameraFullScreenTheme).
        Suggestion: add 'tools:replace="android:theme"' to  element at AndroidManifest.xml:16:5-81:19 to override."</p>
  </blockquote>
  
  <p>I gather it's because im using this "compile 'com.android.support:appcompat-v7:22.2.1'" which is an older version and is conflicting with the theme from the added dependency. </p>
  
  <p>however I want to avoid changing appcompat to a newer version because every activity i have relies on 22.2.1 and the change would be too great. </p>
  
  <p>Are there any ways of working around this error? Or should i just look into another way of creating a square image from camera activity?</p>
