Removed Hostname.parse since it isn't used and isn't actually implemented either
Added setMessage methods and save button
Added status calls to HostessApp
Added error message if we can't load the hosts file
HostnameView triggers save when an item is toggled
HostnameView triggers save when update() is called
Reformat
Updated hostname view so it saves changes made to the target and alias fields
Moved hostnameForm stuff into AddHostnameForm class
Moved UI classes under the UI package so it's a bit easier to keep things organized
Added OSX build scripts
The .app that gets created does not work for some reason, but I think most of the pieces are there.
Ignore the debug hosts output file
