Add --config option and update config files

- Added --config FILE option to specify custom config file path
- Removed [wssht] section from wsssh.conf.example (legacy)
- Created separate wsssht.conf.example with wssht-specific options
- Updated man page with new --config option and mode options
- Updated usage message to include all new options
- Config file validation: errors if specified file doesn't exist
