tdf#134832: Clear the cache directory if it is for another version of the
app
We don't want to use cached scaled icons (and other stuff that might
be in the cache?) if from a potentially incompatible version of the
app. Store the core and online hashes in files in the cache to be able
to compare.

// Having LANG in the environment is expected to happen only when

one's iPad to that
// language, as it might be hard to find the way to set it back to a known
language.
