Sending a friend request should return you to the page you were previously on

[Kristina Hoeppner]

Reported by a user: "When I click on Send Friend request and then request friendship I am returned to page one of the list, not the page I was on (which might have been page 14ish).

It should return me to the page in the list I was on."

This was a quick change so I made a patch for it:

Friend request options return you to correct pagination (bug #852304)

- have got the deny request, remove friend, send message and request
friend options remembering the pagination

- I also altered the code in some places to match the coding layout
in others.

The offset variable gets passed through to form so on return you end
up on correct pagination page rather than beginning of list
