eshell-up

Thanks to @LemonBreezes for implementing the following enhancements in PR https://github.com/peterwvj/eshell-up/pull/5:

• Autoload interactive commands
• Enable lexical binding

This release contains a fix that ensures that the current directory is always skipped when searching for a specific parent directory. For example, assume that the current working directory is /abc/def/ghi/abc/. If the user executes eshell-up a then eshell-up will now change to the directory, /abc/, wheres in previous releases it would stay in /abc/def/ghi/abc/.

This release adds support for finding a specific parent directory without navigating to it. See the README for examples.
