[ticket/11018] Attempt to fix li.pagination alignment issue

This is somewhat kludgy fix for the vertical alignment issue
for pagination contained within a linklist parented li element.
Tested and doesn't seem to impact anything else negatively. May
need further browser testing.

[ticket/11018] Swap prev/next links on pagination to the old order

In the old pagination Prev was left of the pagination and Next right of the
pagination. While moving these blocks, I also removed the whitespaces, which
were introduced.

[ticket/11014] Restore template vars for next/previous links

They were dropped while the function was refactored:

If the block_var_name is a nested block, we will use the last (most inner)
block as a prefix for the template variables. If the last block name is
pagination, the prefix is empty. If the rest of the block_var_name is not
empty, we will modify the last row of that block and add our pagination items.
