Bulk centroid swap

[Stephen Gatesy]

We now work with multiple model sets based on multiple CT scans of the same individual. After tracking data, we'd like to be able to change to a new centroid set rather than do each rigid body individually.

If these could be stored so that a user can just select from sets of centroids, that would be helpful too.

We understand that these can't have differences and still swap, so maintaining consistent point names and numbers and rigid body membership is important.

fixes #85: 3D coordinates of markers can be updated by using the import/export -> import from csv in the pointlist. Note : it simply replaces the coordinates and names in the order the csv file is written. It does not check for the names to match.
