3.0 regression: addMapMenu broke

[Vadim Peretokin]

This works on 2.1 and does not on 3.0:

addMapMenu("create exit stub")
addMapEvent("nw", "createExitStub", "create exit stub", "northwest")
addMapEvent("n", "createExitStub", "create exit stub", "north")
addMapEvent("ne", "createExitStub", "create exit stub", "northeast")
addMapEvent("e", "createExitStub", "create exit stub", "east")
addMapEvent("se", "createExitStub", "create exit stub", "southeast")
addMapEvent("s", "createExitStub", "create exit stub", "south")
addMapEvent("sw", "createExitStub", "create exit stub", "southwest")
addMapEvent("w", "createExitStub", "create exit stub", "west")
addMapEvent("u", "createExitStub", "create exit stub", "up")
addMapEvent("d", "createExitStub", "create exit stub", "down")

It should add a right-click menu to the mapper.
