Add the users HOME in the global config dict.
Review Request #3171 — Created July 2, 2012 and submitted
Add the users HOME in the global config dict. BUG: If the user has set up only one .reviewboardrc in his/hers home directory, it will not be included in the search path for configs. It's contents is returned from load_config_files() and assigned to user_configs in main. How ever this variable is never used in parse_options(). FIX: Add the HOME path to the search path for global configs.
