1. copy multipart mime footer/header (*.mime files)
2. copy template directories

Version

Installation method

from source package

Expected behavior

If creating a new list as copy of an existing one then this should also

1. copy multipart mime footer/header (*.mime files)
2. copy template directories

Actual behavior

Creating a new list as copy of an existing one then this does not

1. copy multipart mime footer/header (*.mime files)
2. copy template directories

Additional information

See PR #1289 for a simple fix
The fix (PR) does this by adding both *.mime files to the list of file.
And by fixing the copy logic to also copy template directories.
