The Editor is very useful for correctly opening a text editor and making changes to some initial input. The current use of Editor is only for getting input for commets.

However, it would also be useful for opening up a text editor on some other existing files or text, for example, in the command rad config edit.

The Editor struct was changed to have two new options, truncate and cleanup, to allow the user of the struct to dictate whether existing text is truncated, and if the underlying file should be remove.

The original new method is now named comment, mimicing the existing construction of a temporary RAD_COMMENT file.

The new version of new accepts any file for the Editor and will open it without truncating or removing the file.

Editor is now used for the rad config edit command.

Changes:

• Mistakenly removed Drop impl, reintroduce and use self.cleanup

Rebase.
