Headings should produce unique anchors so that headings with identical text can still be referred to

The automatic anchors created for the headers aren't always unique.

h1. Introduction
h2. Test Case 1
h3. Conclusions
h2. Test Case 2
h3. Conclusions

There is no way to accuratly link to the last heading (#MyPage-Conclusions) without creating a anchor of my own but that would still break the Table of Contents plugin.

I suggest that either checking to make sure a specific anchor is unique within the page against a list generated while creating them. Adding a hash of the path wouldn't help if the Test Cases lacked their numbers.
