Estimated time of availability instead of time left on the print

[btastic]

Feature Description

It would be great if there was an option, that you could switch what kind of time is showing.

Right now it is just showing the remaining time. Would be cool to look at it and see that it will take until 4pm or something.

So imagine it is 2pm, and the time left is 2 hours 30 minutes.

Instead of showing 2:30 left, you show 4:30pm.

Justification

Easier to remember at what time the print is finished, instead of how much time is left

Suggested Implementation (if you have one)

Make it a setting so you can switch between time left / ETA.
