Set the max ID of menuitems to G_MAXINT rather than 30000, as internally, the server side happily creates ID's greater than this which then wraparound on the client side.
We keep the minimum unchanged at -1, as some consumers addume that < 0 is an error (rather than -1). To make this a bit less fragile, handle rollover on the server side from G_MAXINT to 1, rather than having a signed integer overflow which will just break things a bit later on
