Add support for SSH tunnels, improve password security, and tweaks:

 - Implementation of a new SPSSHTunnel class, designed to closely integrate SSH tunnels within Sequel Pro.
 - Integration of SPSSHTunnel - new connection methods using callbacks, and CMMCPConnection integration
 - Keychain class upgrade to include the new SPSSHTunnel keychain password helper on the trusted access list for new passwords
 - Keychain passwords are now held in memory/UI for only as long as necessary, increasing password security
 - Updated interface to enable/add SSH tunnel functionality
 - Remove old SSHTunnel class
 - Addition of new target for the SSH Tunnel password assistant, addition as a dependency of the main target, and addition to build script to copy into resources directory
 - Fix a keychain password deletion crash
