Absolute redirects

A redirect from introduction.html to /new_location.html matches both /introduction.html, /products/introduction.html and /company/introduction.html

In RSSEO there is no way to specify that only the first has to be matched.
Furthermore if /introduction.html gets moved to /products/introduction.html, you get an ERR_TOO_MANY_REDIRECTS in the browser, because the new file is also matched and you get a circular reference.

Please add some way to specify absolute paths, such that we can match only /introduction.html. For example by allowing {^}/introduction.html, where {^} stands for the documentroot.
