Fix rendering skyboxes to a tile by altering renderSetTarget() & renderRestoreTarget() to set & reset xdim & ydim so that G_ShowView() can render while a render target is set,
and additionally modifying G_SetupCamTile() to call EVENT_DISPLAYROOMSCAMERATILE after calling renderSetTarget()
Add updatesectorneighbour() and updatesectorneighbourz() and make them accessible to CON to allow searching for nearby neighbouring sectors from a known sector.
These updatesector counterparts are more performant for tasks that require determining whether nearby sectors exist at a point as they will not exhaustively search the map. This also leads to more correct behaviour when sectors are disjoint, as queries will breadth-first search neighbouring sectors rather than risk accidentally stumbling first across accomodating disjoint sectors.
Add EVENT_RESETGOTPICS which gives scripts the chance to reset gotpics (and similar effects trackers) for effects that run in EVENT_DISPLAYROOMS.
EVENT_RESETGOTPICS is called after the last call to EVENT_DISPLAYROOMS in a frame, but before any engine-side calls to renderDrawRoomsQ16()
