provide conditional last/first

if {0} as in paging.banner.full may show the last but it also may not.

Suggestion, create a
  - paging.banner.page.link.last.conditional that can be addressed as {8}
  - paging.banner.page.link.first.conditional that can be addressed as {9}

{8} only is different from "", i.e. showing "paging.banner.page.link.last.conditional" if the link in {4} is not also part of {0}
{9} only is different from "" if the link in {1} is not also part of {0}

Similarly, there should be a
  - paging.banner.page.link.next.conditional that can be addressed as {10}
  - paging.banner.page.link.previous.conditional that can be addressed as {11}

{10} only is different from "" if the link in {3} is not also part of {0}
{11} only is different from "" if the link in {2} is not also part of {0}
