Show a message after pressing CTRL+S to save a file

Show a simple 'file.txt was saved successfully...' or similar message in the status bar after pressing the CTRL+S hotkey to save a file.

The interface right now shows no feedback to the user after a file is saved. This results in me sometimes pressing the hotkey multiple time to make sure that I've actually saved the file.

This would be very nice, especially when using Tilde via SSH where not every keystroke makes it through. If editing something critical, I'll sometimes cat the file after closing it to make sure my changes were saved. A confirmation message would save me that step.
