I have replaced OpenPilot in the About menu with LibrePilot. I didn't use the DEFINE which has been set by the Makefile, as I am not sure how to deal with the translation strings. ~~I have also changed the OpenPilot to LibrePilot in the translation files.
I haven't dealt with translations before - I am assuming I don't need to do any post processing since I didn't make any significant changes.~~ Reverted as they were changed in error!
If this is useful, can someone please commit it? If not do let me know why - I need to learn!
