renaming a dir hides its contents

[menaquinoneK2]

1. Create a dir on host eg. c:\1
2. Create a file(or dir!) inside the c:\1 dir, eg. echo a>a
3. open explorer inside the sandbox
4. look inside c:\1, you see file a
5. go back out and rename 1 to 2
6. go inside 2, there's no a file anymore

now, rename it back from 2 to 1 and contents are back
if you made something new in 2, then after renaming 2 to 1 their contents are now seen as merged

bugs bugs everyware....

When I try the same thing with the registry editor I cant rename a key that exists on the host also not good

but how to fix that... I mean
a) create a full copy on rename
b) store some metadata indicating the new name

I think we should go with B even though its more work

This fix is ready and will be added in one of the upcoming builds, may be not the next as that might be only a minor release with some fixes only quickly followed by a large experimental release
this feature will need you to enable it with UseFileDeleteV2=y

Also I haven't yet sorted out the handling of snapshots not sure if that will be done till the release.

With this change sandboxie will no longer create dummy deletion mark files/folders, instead it will maintain a data file of deleted and also of renamed paths.

Also currently renaming a file always creates a boxed copy, in a later stage that could be improved to use the same relocation mechanism as will be now used for folders.
