get rid of console thread for OpenRecoveryScript

- CLI commands run in a threaded action "twcmd"
- Console is displayed via "singleaction_page"
- move ORS execution code from GUI action to OpenRecoveryScript class
- remove unused function gui_changePackage
- don't change PageManager package in home action
- fix that /tmp/openrecoveryscript was not deleted after execution
