#91 Struct vectors don't generate _x/_y/_z members

[Paril]

These are quite useful on fields (ent.origin_x, for instance), but if inside of a struct, there's no _x/_y/_z generated for them (ent.s.origin_x generates an error)

Yes, this indeed still seems to be a problem.

Apparently this is by design, as it uses up extra fields.
The only compromise I could think of is adding a (expensive) flag that will always allocate those extra fields, but as Spike said people should rather just use .x/.y/.z or [n].
