Implemented handling of URLs with pagination segments for PagePathHistory module

[bfncs]

The core module PagePathHistory didn't handle URLs with pagination segments until now.

Steps to reproduce the problem

1. Create a page with working pagination handling and markup so, that the following URLs are handled by that page:
   • /objects/
   • /objects/page2
   • /objects/page3
   • …and so on.
2. Enable the PagePathHistory module in the admin.
3. Rename the objects page to objects-new.
4. Requesting the now deprecated URL without pagination segment /objects/ works flawlessly by redirecting to the now correct URL /objects-new/ .
5. Requesting one of the now deprecated URLs with pagination segment, e.g. /objects/page2 leads to a 404 Page not found error instead of redirecting to the now correct URL /objects-new/page2.

Patch

This patch adds basic handling of URLs with pagination segments to PagePathHistory. Redirection after changing page URL prefixes is not supported, though.
