- introduced AuthenticatingConnectorService as a superclass of AbstractConnectorService
- moved almost all methods from AbstractConnectorService to AuthenticatingConnectorService. AbstractConnectorService now handled the creation of the StandardCredentialsProvider for all subclasses.
- moved AbstractConnectorService back to UI with the intention of renaming it StandardConnectorService
- moved requiresPassword, supportsPassword, requiresUserId, and supportsUserId back to IConnectorService from ICredentialsProvider.
- removed SshCredentialsProvider and DStoreCredentialsProvider, their connector services can now use the StandardCredentialsProvider
- Introduced ICredentialsProvider implementations
- Refactored some AbstractConnectorService methods into the credentials providers
- Further simplified the concrete connector services
- made more methods final and explicitly indicated where overrides are allowed, required.
1) Create new ICredentials, ICredentialsProvider, and SuperAbstractConnectorService (temporary)
2) Move most non-password methods to SuperAbstractConnectorService.
3) Rationalize the user of ServerLaunchers.
4) make internalConnect and internalDisconnect abstract.
Updated all subsystem configurations and connector services.
Rewrote login dialog to make password or user id optional.
Rewrote AbstractConnectorService.promptForPassword to take advantage of new configuration parameters.
