2.8 Category Admin Fix

[ghost]

URL changes in 2.8 was causing draggable not to work in the category admin.

So the following URL index.php?/cp/admin_content/change_category_order?cat_id=1&group_id=1&order=up'was getting split into ["index.php?/cp/admin_content/change_category_order?cat_id=1", "group_id=1", "order=up"] with the issue being the the cat_id parameter.

This fix changes the split seperator into a regex so it accounts for both '?' and '&', which now returns ["index.php", "/cp/admin_content/change_category_order", "cat_id=4", "group_id=1", "order=up"] fixing the issue.

Thanks for the fix, Keiron. Not sure what a pull request as simple as this can't be merged already.
