Some background. At least in our implementation, removing each
individual item is significantly slower than removing and recreating
the objectStore. It's also significantly slower than a 'clear'
function is. And while tearing down and recreating the objectStore
works, it's fairly complex if there are multiple indexes on the store.
Adding a clear() function, while redundant, should make things easier
for developers while adding very little work in the implementation.
I think there is a bug in the above proposal though. clear() should
return a IDBRequest. However the .result of the request should likely
be null.
