Small comment added to hash.py.

Note that we use sha256 as hasing function on all "db storeables" items (such as cache or storage). The probability of clash with the low length keys that we use is, basically, 0, and it's fine this way. Althouth there is faster hashing methods, the los usage and the db itself maky insignificant if it's faster or not

     Note that replacing the algorithm used here will force to invalidate all previous generated
     entries. In the case of cache, this is not a problem, but in other cases, it could be.
