#88 Don't DESTROY on move, DELETE. Very bad.

[Jeff Mounce]

When you DELETE a class/module in Eclipse 2.x using
v1.5.0, it does the proper thing and DELETEs the file
from VSS. However, when you do a MOVE in Eclipse
(refactor), it DESTROYs it in VSS.

This is very bad and evil since it causes old, labelled
versions of the software to be invalid.

Ultimately, this would be an option that the user could
set: whether to destroy or not on a move or delete.
