Set IFC en masse

[shorter]

It would be very useful if when we create our own components as symbols, to be able to select all symbols and set IFC category to all symbols selected, rather than one by one.

That would be nice. They could also improve the data manager in that regard. Atm it is tedious to assign ifcobjecttypes to symbols there as well and set up the mapping.

Transferring IFC data from one symbol to the next (using the eyedropper tool) works for that instance but not for all instances thereafter.  What would be useful would be to have an option to transfer IFC data from one symbol to another and have it behave in the same way as though I had selected the symbol in the resource manager and set it's IFC data via the right-click menu.

We need in general a more comprehensive way of working with large resources. We have a batch renaming command now for all of them, but there is potential for more batch commands.
