some enhancements to cluster quiver interact

[fchapoton]

• make it really work on python3

• auto-reduce the mutation sequence (mu_i is an involution)

• interactive choice between spring and circular display

• adjust the vertex colors (more pastel)

Thanks for taking care of this! I don't have any new version of sage, but I am sure Travis has :-)

Probably. If you want to quickly fix that, go ahead, and we can reset to positive.
