Add numeric values to progress bars

[cionescu]

While printing there is a small box with the "Printing..." message and below it a progress bar. It would be very helpful to see the actual remaining time as a number, say 15 min, without having to open the machine control for it.

Similarly, when displaying "Heating bed" and "Heating extruder" progress bars, perhaps add another line below or above the progress bar with the actual / target temperatures, such as 180 / 210C. Again, all this info can be readily found in the machine control panel but would be very helpful to see it in the main window.

Thank you.

In addition to the heating info it would be great to see - if you are using 2 Extruders - both tempeartures in the Machine Panel without using the Tool Dropdown Menu (where I alwas get a warning window)
