Fix movable objects.

Описание: Thanks to this guy and his video,    • Richard Burns Rally - RBR-WRC New function...   , which clearly shows dynamic objects in btb format, I was motivated to test an idea that has been in the air for a long time. I have repeatedly convinced myself that the bad functionality of btb tracks is not the sin of the RX plugin, but of the btb editor, which incorrectly fills in object parameters when exporting. And so it is. It is enough to change a couple of values (per Instansed Mesh) in a text file to return dynamic properties to objects.
