Use wxSelectionStore in wxDataViewCtrl generic implementation.

Browse Source 
This makes the code (slightly) shorter and more clear and is more efficient as
selecting all items in wxDataViewCtrl is now a O(1) operation instead of being
O(N), where N is the number of items -- and the latter could take quite a long
time (and consume non-negligible amount of memory) for large N.

Increase the size of the virtual list control from 1000 to 10000000 in the
sample to show this.
