remove pending spec

Full board win scenario feels redundant; not gonna do it.
DRY @scope.board to @board in specs
remove unecessary assertion on @board

Tests will already cry loudly if @board is undefined.
removed TODO; not so smelly

That the board model is a flattened 3x3 array is actually
the public API and corresponds with using a UL based grid
instead of a TABLE to render it in the template.
OCD makes me align all the things
AngularJS convention is camelCase, not snake_case
refactor `playerMarks[i]` into `players[i].mark`
