Levelname.mis.decals files spam

[Duion]

When a server hosts a level that is not present on the client in that folder or with that name, then for the client a levelname.mis.decals file is generated and the according folder if it is located in a new folder. This should be disabled somehow. The automatic generation of that file should be disabled and it only should be generated if you save the decals in your editor, or just don't send it to the client or generate it on the client.
