Better formatting for firmware file name

[JPHutchins]

FW file names may be very long, so the display during upload/upgrade can be improved in 2 ways:

1. Display only the file name instead of the given path
2. Display the file name on a line above the progress bar so that it can still be long. Replace the current location of the file name with the transport ID but add a character limit. If the transport ID exceeds the character limit, display the first and last characters with ellipsis representing the missing characters.

This will be important when multiple devices are being updated at the same time. The FW name will be displayed once and each transport gets its own progress bar.
