Multiple changes in the appearance of ultidisplay

- progress bar now in the message line during print (working on an on/off switch stored in the eeprom)
- auto home with 5 mm up at the end (needs to be fixed for not inversed printers)
- reversed sorting of files on the SD-card (makes it quicker to print the file that was added last)
- timer stops at the end of print (most people would like to know how long it took to print)
- added a visual "<" sign at the end of submenus where a value can be selected, so users know where they are

Hi Daid,
I deleted the fork and remade it.
Hopefully this time there are only the files that are needed in the pull request.
All not necessary files are not committed from my local repro (README.md and configuration.h) , so I think it should be fine.
I also reversed the finished printing back to Partial release. I need to find the right place for it.

Cheers, greengecko
