Include an icons in ion-item on left

Hello,

It will be helpful to support icons on the left side for list items, the same way images can be used on the left.

Currently icons are left aligned via the following code 

and your main.html look like:-

 <ion-view view-title="main">
 <ion-content>
<ion-list>
<ion-item class="item-icon-left"> <i class="icon ion-document-text"></i>item-icon-left </ion-item> <ion-item class="item-icon-left"> <i class="icon icon ion-email"></i>email </ion-item> <ion-item class="item-icon-left"> <i class="icon ion-document-text"></i>item-icon-left </ion-item> <ion-item class="item-avatar"> <i class="icon ion-document-text"></i>
document </ion-item> <ion-item class="item-avatar"> <i class="icon ion-document-text"></i>item-avatar </ion-item> <ion-item class="item-avatar"> <i class="icon ion-document-text"></i>item-avatar </ion-item> </ion-list>
</ion-content>
<ion-view>
