[0.4.7][EXPLORER] Handle WM_CONTEXTMENU message in CNotifyToolbar and BN_CLICKED notification in CSysPagerWnd.

Browse source 
With these, we generate the WM_CONTEXTMENU and NIN_(KEY)SELECT
shell icon notifications that applications expect when they handle
shell notification icons with uVersion >= 3.

This fixes in particular the previously unresponsive icon of KVIrc 4.x,
and more generally *all* the notification icons of Qt applications.
CORE-10605 #resolve

fix picked from 0.4.9-dev-587-g 4127024b0d
