Made several improvements and fixes for the File DOP. This includes better performance for files with large numbers of objects, proper loading of group information, and better handling of creator node information which will make it easier to use File DOPs within HDAs.

Solver DOPs no longer have an activation field. They are always active. They also no longer have a second input (which was used for attaching data to all objects piped into the solver). Now there is just the object input, and any number of data inputs which are attached as subdata to the solver. The Unique Data Name parameter is now off by default for all Solver nodes, making it easier to use Apply Data nodes to associate a solver with an object.

The Partition DOP now behaves more like the Partition SOP, by placing each simulation object into one or more groups based on an expression. The old behavior of the Partition DOP has been moved to a new DOP called Split.
