BUG fix listview not working with IE9

To reproduce:

1. Using IE9, go to demo.silverstripe.com
2. login
3. go to Pages
4. switch to listview
5. expand pages to get to one with pagination (e.g. Pages > Features > Listview)
6. go to next page

Expected: you go to the next page
Actual: it jumps you back to the home page

Fix: this fix passes parameters stored in the hash part of the url, which IE9 and below rely on for PJAX.
