title: Sweet Alert Dialog ic_launcer is packaged in version 1.3 and causing compiling issues
body: <p>When including Sweet Alert dialog in the project, I encountered an issue which caused comilation issues, due to a duplicated ic_launcher dialog which was packaged in the library</p>
  
  <pre><code>Error:Execution failed for task ':app:processDebugManifest'.
  &gt; Manifest merger failed : Attribute application@icon value=(@mipmap/ic_launcher) from AndroidManifest.xml:7:9-43
      is also present at [com.pnikosis:materialish-progress:1.0] AndroidManifest.xml:13:9-45 value=(@drawable/ic_launcher).
      Suggestion: add 'tools:replace="android:icon"' to &lt;application&gt; element at AndroidManifest.xml:5:5-22:19 to override.
