Instant crash when deleting bitmap + copy from materials.

[rene_rapati]

Problem: Rhino instantly crashes when deleting multiple bitmaps from a material when one of the bitmaps is a copy.

Steps to reproduce:
- Start a new document in Rhino;
- Open V-Ray asset editor;
- Create new Generic material;
- Add a bitmap in the Diffuse slot. (for instance 'Noise A');
- Add a copy of this bitmap to another slot (For instance 'Opacity');
- Click on the arrow next to the material to show all the bitmaps attached to the material. ('Noise A' and 'Noise A#1' in this case);
- Select them both and delete them;
- Instant crash!

This also happens with materials from the Cosmos browser.
The problem is not limited to the Diffuse slot, it happens when one of the bitmaps is a copy and the original gets deleted.

As a workaround It is possible to delete the bitmaps one by one without crashing Rhino.

From the release notes of update 2.3:

Deleting multiple maps of the same texture type simultaneously no longer causes a crash

Just tested this with the 2.3 update and I'm happy to say the steps posted earlier no longer cause Rhino to crash.
