The progress bar will now be updated during image backups, restores and during image flashing (except for sparse images which will require significant changes to libsparse, and except for mtd nand using flash_utils). The progress bar will now be updated mid-file for file systems (tar) so the user will see changes even during large file backup / restore. Add a new progress tracking class to simplify handling of progress bar updates. The class will only update the progress bar 5 times a second to reduce the CPU load from updating the GUI frequently which does affect backup times.
