New rename-project command.

The `rename-project` command will rename a project and update all of the action
items associated with that project.

* Fills in some missing information in the online help.
* Fixes a bug in the finGtdRootDir function. It was not properly handling
  relative paths.
* Fixes a bug where the reconfigure command was referring to the wrong
  configuration file.
