Before this commit, we compute the hash on each request, to know if we need to
download the file from the frontend or if we can use cache.
Now we store the hash computed in cache. The cache will be invalidated when we
touch one of these translations (openerp-web in the comments) or when you
install a new lang (already the case).
+ avoid to use read on a record, since it will not use the cache from record.
