Support for display suite cloning, exporting and importing

That's awesome! Thank you so much!

Patch couldn't be applied with patch manager though, so I had to fix it before applying ("a/" and "/b" was missing):

diff --git a/bundle_copy.module b/bundle_copy.module
index 95282f94d26699364d39197220ad5848b330967f..bc93b19f321ee9df1f2f66c1a33386a9bd2e38e1 100755
--- a/bundle_copy.module
+++ b/bundle_copy.module

Provided patch in #1 works well for me also (to correctly apply the patch, changes in #3 are needed).

Please notice:

1. some basic bundle properties are not cloned (e.g. "publishing options" and "multilingual support" options, "display settings" and "menu settings")
2. View modes in cloned bundles are not activated automatically (you have to do this manually, but once done this, all fields and configurations appears)
3. If you have some DS custom block regions in the original bundle, these are not cloned and you have to recreate these in the cloned bundle (I think this is ok because block regions needs different machine names)

Thank you very much for this useful patch

Added fixed patch and it worked also for me. Tried it out with commerce product and content types. This didn't enable (copied) custom view modes but this is not a big problem at this point.

Patch applied cleanly but the Full Content display mode, which I was hoping for, didn't get copied. After I enabled it manually it didn't have any of the configurations made on the source node type.

If this approach would be better i'd be happy to provide a patch for that instead.

@thtas That sounds like a good idea. Would be able to provide such a patch for 7.x-2.x?

Moving to the new Bundle Copy Display Suite module.

Here's a re-roll of #5 against the 7.x-2.x of Bundle Copy.
