grid column resets are missing

[pburgmer]

All grid column reset classes like .col-md-offset-0 are missing in 3.0.2.

Affected:
$class: all classes (sx, sm, md and lg)
$type: pull, push and offset

They are missing in bootstrap 3.0.1 also but were added back in 3.0.2 However in sass-bootstrap 3.0.2 they are still missing.

Example:

Seems the loop index is starting with 1 instead of 0 within mixin make-grid. In mixin calc-grid there is a condition for not creating $type = width with index 0. But calc-grid will never get called with 0 at the moment.
