Add trailer as commit property
With the command `git interpret-trailers` git provides a way to interactwith trailer lines in the commit messages that look similar to RFC 822e-mail headers (see:https://git-scm.com/docs/git-interpret-trailers).The new property returns those parsed trailer lines from the message asdictionary.
