Changed leaderboard ID

For the release we're resetting the leaderboards. GPGS doesn't allow
resetting so we're deleting the old board and adding a new one with
a new ID.
Added 'Hexciting' achievement.
Add Total Annihilation achievement
Add 'Everyones a Winner' achievement
Add 'Hello World' achievement
Add 'Breakin the law' achievement
Shuffle achievement Ids

GPGS doesn't allow changing certain fields after publishing an
achievement.

To get around this, we renamed and changed the text for an existing one
and added another achievement.
Add 'Phoenix Down' achievement
Add 'Now youre gettin it' and 'millionaires club' achievements
Add 'Event Horizon' Achievement
Add 'Last Man Standing' Achievement
