Fix Absolute Links

When working on different environments, such as development and production, absolute links are often accidentally entered in a page's content. This can happen through either copying and pasting an internal URL or simply typing it in, and it poses a problem when the website is moved to a different environment - especially production.

Having an absolute link pointing to a development environment when a website is live is certainly an unwanted situation, and that's what this module aims to prevent by:

1. Letting the user select which content types he would like to search for absolute links
2. Presenting a list of pages that contain absolute linking in their content
3. And giving the user the option of automatically fixing the links - task which is usually tiring if performed manually
