pagination refactor

[rahgurung]

THIS PR closes 2 BOUNTY ISSUES

closes #397 closes #398
Fixes

1. Issue with leaderboard #397
2. Error when leaderboard empty #398
3. Clicking on Last doesn't take you on last page.
4. ... feature wasn't working even though code was there.

I removed Last and First button here because first and last page links are always there. Let me know if you want to have Next and Prev text instead of those arrows.

No volunteer I guess, Can I self test this and comment the detailed report here with screenshots?

Will I get the testing bounty also if I test my PR myself?
