Added documentation for wxItemContainer class; moved methods docs

from wxControlWithItems there and fixed errors in them.

@class wxControlWithItems
@wxheader{ctrlsub.h}
This class is an abstract base class for some wxWidgets controls which contain
several items such as wxListBox, wxCheckListBox, wxChoice and wxComboBox derive
from it.
wxItemContainer defines an interface which is implemented by all controls
which have string subitems each of which may be selected.
It is decomposed in wxItemContainerImmutable which omits all methods
adding/removing items and is used by wxRadioBox and wxItemContainer itself.
It defines the methods for accessing the controls items and although each of
the derived classes implements them differently, they still all conform to the
same interface.
Note that this is not a control, it's a mixin interface that classes
have to derive from in addition to wxControl or wxWindow.
The items in a wxControlWithItems have (non-empty) string labels and,
optionally, client data associated with them. Client data may be of two
different kinds: either simple untyped (@c void *) pointers which are simply
stored by the control but not used in any way by it, or typed pointers
(@c wxClientData *) which are owned by the control meaning that the typed
client data (and only it) will be deleted when an item is deleted
(using wxControlWithItems::Delete) or the entire control is cleared
(using wxControlWithItems::Clear) which also happens when it is
destroyed.
Finally note that in the same control all items must have client data of the
same type (typed or untyped), if any. This type is determined by
the first call to wxControlWithItems::Append (the version with
client data pointer) or wxControlWithItems::SetClientData.
Examples: wxListBox, wxCheckListBox, wxChoice and wxComboBox (which
implements an extended interface deriving from this one)
