Changes

Revert back to old naming

Renaming causes too many issues and corrupts the global config so that
the delta V and vessel info windows disappears in the VAB.

Unfortunately, corrupted windows will need to be manually fixed by
editing mechjeb_settings_global.cfg and setting showInEditor to
'True' for the 'Vessel Info' and 'Stage Stats' windows.
