Fix crash in DDays "wake" map, #978

Browse source 
the HunkAlloc size calculated in calTexinfoAndFacesSize() was too
small because that map has a *massive* water poly.
Unfortunately it's not feasible to calculate the correct size
(it depends on the size of the poly, for which I'd need the vertex
coordinates, but to get them I'd have to load them first, which requires
the allocation...), but allocating 5MB extra (instead of 1) made it work
