Fix 418. Remove redundant comma.
Fix #417. Calling grid.sort no longer results an error and the column's direction will be set correctly now. The  option has also been removed from the insertColumn and insertRow for their uselessness.
Fix #420. The default comparator should not sort the model cids lexicographically.
Fix #421. Give correct context to _renderOptions and user underscore's indexOf because IE8's array does not support indexOf.
Throw an error early if the direction is not ascending, descending or null
Fix #422. Remove sort caret for column when sort on a different column
