86BoxManager crashes after trying to delete a VM with read-only files in the directory

Attempting to delete a VM with some read-only or protected (in use) files in the directory causes the manager to crash. For instance, I installed Windows 3.11 and extracted the disk to a directory but deleting the VM yields a crash.

I'll fix this so it's handled properly, but common sense also applies here - don't try to delete things that are in use or read-only. The VM directory should be writeable and not in use, same goes for everything inside as well.

This has been fixed in version 1.5.1.
