Added Status "pending" to Bulk Edit dialog as it was previously available only in the grid built-in editor for the Status field.
Fix StockStatus not saving in some cases.
Fixed not saving the change of Product Type, when option "Use API calls when possible" is enabled.
Fixed an issue with the grid where the current grid changes aren't commit when the grid loose focus. For example, if you edit a cell and then click "Save Changes" it does nothing as the grid didn't commit the changes when lost the focus and therefor "Save Changes" doesn't execute.
