increase viceroid sight & scan range

Viceroids are kind of passive. Would like them to be a bit more aggressive when units are nearby.
return orca range to 5

Problem: orcas in small groups will sometimes get in each other's way and be stuck outside of range. The old range was 5, but this was to nerf large groups.

Orcas have been nerfed in several ways. One of the ways was to reduce their range from 5 to 4. However, when the range reduction is coupled with all the other nerfs, it seems a bit too much. Orcas are fairly vulnerable now that air defense has improved.
gave SAM missile a spread, to match MSAM.

To increase power vs. large groups of helis
reduce orca reload time, similar to earlier levels

Orca was over-nerfed with respect to reload time. It was not effective at finishing off vehicles and buildings if it ran out of ammo, because it took way too long to reload.

Its reload time has been set to the old one, but now it reloads 2 pips at a time, so it is slightly slower than originally, but not by much. It's a bit OP when it loads one at a time, it seems.
