add option to disable animations, use in dashed border overlay

There are use cases when it is useful to disable animations (using
LO in remote display when the bandwidth is limited). This adds an
option that will allow to disable all animations. Currently only
animation when copying cells in Calc (dashed border overlay) uses
this option.
