Display a more detailed window during the milling protocol execution

[CraignRush]

Display maybe:

• Remaining and passed time, overall and per lamella
• Step within milling protocol (thickness, current, time, patterning strategy (maybe a 3D-model?))
• Calculate the next "Dewar Refill Timepoint'"
• Progress of positions 'x/y'

Buttons:

• Skip this lamella
• Stop lower/upper pattern resp. continue with next step
• An abort button that doesn't crash the program all the time ;)
• Pause
