Version 1.2

This Update introduces two new features to this extension:

 - **Anchor Label**: Adding an optional custom label for the links on the publish pages
 - **Display URL**: Display URL in entries table (Instead of anchor label)

### Behaviour:

**Page Publish Entry:**
  1. If an "Anchor Label" is set it is used as the title of the preview link.
  2. If no "Anchor Label" is set the preview link title will fall back to "Preview".

**Page Entries Table:**
 1. If "Display URL" is checked the full URL will be shown as the title of the preview link.
 2. If "Display URL" is not checked, but an "Anchor Label" is set this will be used as the title of the preview link.
 3. If "Display URL" is not checked and no "Anchor Label" is set the preview link title will fall back to "Preview".

In addition to that I made the entry id available for url formatting and did some small changes & additions in the readme.

It's working fine for me and I tried to adapt as much of your coding-style as possible, but as I'm not an experienced php-coder it might be better if you could review these changes rather carefully ;)
