Handle old global vector compontents.

Browse source 
In the original save gave format, global vectors were saved as individual
components rather than as a single vector, using the _x/_y/_z tags on the
vector name. However, recent qfcc completely dumped vector components as
separate defs, so old save games would have trouble loading with progs
built with a recent qfcc. Thus, do the component translation if necessary.
