omit externals ignored when create and switch to new branch

[Christopher White]

If you do the following;

-Branch\tag

-check box; switch working copy to new branch tag

Then the externals are automatically checked out. I have Settings\Advanced\IncludeExternals=False

If you do the following, it works correctly:

-Branch\tag

-Switch

-Select "Omit Externals"

I think we just need the "Omit externals" check box available in the "Branch\tag" dialog.

Thank you.
