Morph atoms don't move if alt locs are present

Shows atoms that do not move in morph with enormously long bonds. These atoms have alt locs. Coordinate sets cannot have altlocs according to Eric.

Morph command probably needs to remove alt locs from the trajectory.

Fixed; implemented a 'dealtloc' structure method that morph calls after copying the starting structure

dealtloc is a pretty cryptic name.  Maybe it could be changed to the more self-explanatory delete_altlocs?

I thought about it for awhile before calling it "dealtloc".  To me, delete_altlocs sounds too much like the atoms with altlocs are being deleted entirely.  It's a rarely used function anyway so the name probably doesn't have to be perfect.

I think the interpretation of delete_altlocs as deleting alternative locations and not the atom itself is what the name suggests.  It makes no sense to selectively delete atoms that have altlocs, so I can’t imagine anyone trying to use it to do that.  And the name is much clearer than dealtloc (which I at first parsed as “deal”  or “dealt” rather than “de-".  But it is of course your call.

Okay, changed name to delete_alt_locs.
