title: How to align buttons in the MdDialog md-dialog-actions block
body: <p>In the MdDialog's md-dialog-actions block, is it possible to align a button on the left while there are two buttons aligned to the right?</p>
  
  <p>Here's a <a href="http://plnkr.co/edit/zhzxqPANDZagcN1znTzL?p=preview" rel="noreferrer">plnkr</a> of some stuff I'm trying to do.  Say, on the first modal, how do I separate the Yes and No buttons? (See the common-model.component.ts file) (This plnkr has some other issues to it that I'm still working on. But it doesn't involve this question.)</p>
  
  <pre><code>import { Component }   from '@angular/core';
  import { MdDialogRef } from "@angular/material";
  
  @Component({
      selector: 'common-modal',
      template: `
        &lt;h2 md-dialog-title id="modal-title"&gt;{{ title }}&lt;/h2&gt;
        &lt;md-dialog-content&gt;
          &lt;p class="dialog-body" id="modal-message"&gt;{{ message }}&lt;/p&gt;
        &lt;/md-dialog-content&gt;
        &lt;md-dialog-actions align="right"&gt;
          &lt;button md-raised-button 
                  md-dialog-close 
                  id="modal-close-btn"&gt;
            {{ buttonOptions.closeText }}
          &lt;/button&gt;
          &lt;button md-raised-button 
                  *ngIf="buttonOptions.enableNext" 
                  id="modal-next-button"
                  (click)="dialogRef.close(true)"&gt;
            {{ buttonOptions?.nextText }}
          &lt;/button&gt;
        &lt;/md-dialog-actions&gt;`,
  })
  export class CommonModalComponent {
      /**
       * {string} The text for the header or title of the dialog.
       */
      title: string;
      /**
       * {string} The text for the body or content of the dialog.
       */
      message: string;
      /**
       * closeText  {string}  The text of the close button. (No, Done, Cancel, etc)
       * nextText   {string}  The text of the confirming button. (Yes, Next, etc)
       * enableNext {boolean} True to show the next button. False to hide it.

      buttonOptions: {
          closeText: string,
          nextText?: string,
          enableNext: boolean
      };
  
  
      constructor(public dialogRef: MdDialogRef&lt;CommonModalComponent&gt;) { }
