Hi all,

This patch adds testing and default implementations for
Tree.get_file_lines and Tree.get_file_text.  Tree.get_file_lines is
important to supply, because it is easy to make mistakes if it is not
available.  Specifically, it is tempting to use file.readlines, but this
has platform-dependent behaviour.

Also, this adds a path parameter to both, mirroring get_file.  It's
becoming apparent to me that WorkingTree and PreviewTree ought to
provide reasonable access to unversioned files, so I hope to make
get_file, get_file_lines, and get_file_text accept None for the file-id
in a future revision.
