Bugfixes for Motion Path drawing/updating in light of the recent changes:

* Added proper "update" operators in place of the abuse of the calculate
operators, so now the display ranges won't get overwritten everytime (with the
default values) you go to update the paths.

* Display range settings in properties editor now actually work. Before, the "In
Range" mode only displayed the entire paths.
