Improve explanation of maximal number of wxListBox items in the documentation.

Don't say that it's limited -- because, strictly speaking, it isn't -- but
mention other controls that are better alternatives for large numbers of items.

+    List box elements are numbered from zero and while the maximal number of
+    elements is unlimited, it is usually better to use a virtual control, not
+    requiring to add all the items to it at once, such as wxDataViewCtrl or
+    wxListCtrl with @c wxLC_VIRTUAL style, once more than a few hundreds items
+    need to be displayed because this control is not optimized, neither from
+    performance nor from user interface point of view, for large number of
+    items.
