* Initial working version of the flash gui - Renamed to goxf - Needs 'sudo' to be enabled to the user without password - Identify and ban piece files while including them in the list - Support for flashing multiple piece files - progressbar and warn/error messages handled - Supports reboot mobo command

* Make qmode be functional
* Lot of hardcore fixups on squeue_open
  - Should work now everywhere fine asumid UID 1000 as allowed user
  - Reduce timeouts
  - Add push2 method
