title: Changing toaster class from the controller toaster.pop()
body: <p>Im using toaster for angular:</p>
  
  <pre><code>https://github.com/jirikavi/AngularJS-Toaster
  </code></pre>
  
  <p>This is my directive:</p>
  
  <pre><code>&lt;toaster-container toaster-options="{'time-out': 3000}"&gt;&lt;/toaster-container&gt;
  </code></pre>
  
  <p>all good here, what i want to do is this, right now it shows me all the msgs in right top corner of the screen, which is what i want (it's also the default behavior), i want to do (for some particular msgs) this:</p>
  
  <pre><code>&lt;toaster-container toaster-options="{'position-class': 'toast-top-full-width'}"&gt;&lt;/toaster-container&gt;
  </code></pre>
  
  <p>Now i can't seem to find any option to change the position class from the pop() method:</p>
  
  <pre><code>https://github.com/jirikavi/AngularJS-Toaster/pull/40/files?short_path=04c6e90
  </code></pre>
  
  <p>What i currently have is simple msgs like:</p>
  
  <pre><code>toaster.pop('success','Redirecting to paypal');
  </code></pre>
  
  <p>And i need something like this:</p>
  
  <pre><code>   toaster.pop('success','Redirecting to paypal',{'position-class':'toast-top-full-width'});
  </code></pre>
  
  <p>What should i do?</p>
