Missing export of ITdDataTableSelectAllEvent

[jotatoledo]

Hi,
I was just using the data table component and realized that I wasnt able to import the event ITdDataTableSelectAllEvent.

The problem is caused by a missing export in the data table module.
Currently in data-table.module.ts (covalent/core is 1.0.0-beta.2):

export { TdDataTableComponent, TdDataTableSortingOrder, ITdDataTableColumn, ITdDataTableSelectEvent} from './data-table.component';

The fix would be:

export { TdDataTableComponent, TdDataTableSortingOrder, ITdDataTableColumn, ITdDataTableSelectEvent, ITdDataTableSelectAllEvent } from './data-table.component';
