Package name change breaks old data

[rdoeffinger]

Renaming imagePositionLocator to ImagePositionLocator means that old tracks can no longer be loaded, due to Android's deserializer being broken/stupid (Java's has no problems with that since ages).
While it seems there are (fairly horrible) workarounds, that would mean implementing them in all places that deserialize data.
Maybe the rename should just be undone?

Uff ... however should the app ever be used by a few more people than renaming then would also be impossible. Do you already have that many maps?

Don't worry. This was mostly a "wait, this doesn't seem right" case for me.
But these kind of things make me double weary of using the built-in serialization (besides the masterpiece of it being both slow and binary and not supported by anything but Java really).
It might worth looking into something like Jackson to write a "nice" (well, relative term) JSON file instead.
