DTActionSheet: Moved block execution to clickedButtonAtIndex:

Moved block execution from 
    - (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
to
    - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
and added corresponding delegate checking and bitmask updating code.

Avoids a very noticeable delay in executing the requested action.
