Integrates config support into NMSSHSession. Adds support for “user” in config files and fixes the case where multiple NMSSHHostConfig’s match a single host name.
Rename synthesizedConfig to hostConfig, use setFoo: instead of property syntax for assignment
Rename one missed instance of synthesizedConfig to hostConfig
Rename hostCOnfig to matchingHostConfig that was missed
