Automatic transfer of old configs to new version

[Bushmanni]

While I understand the need to ditch old controller config files when new features require update to the file structure most of the information content still stays the same, like which joystick button does what. It's pita to redo all the configs for all the aircraft always when a update happens. While I hope there would be less of this with new auto update I still suspect the config files need to be updated just as they have been previously. With more aircrafts coming it's becoming unfeasible to redo all the configs manually and as such there needs to be automatic system for translating and transferring the old config files to the new system. Otherwise we are soon in a situation where it's completely impractical to do any configuration within the game as it's already testing nerves.
