Jonas Borgström 80a2a4113f Revert "Reduce memory usage when backing up many small files" 
The memory usage should be reduced a fair bit by #90 so this
might not be needed anymore. Or at least not enabled by default

Jonas Borgström 7f9fe03917 cache: Reduce file cache memory usage (#90) 
The memory usage is reduced at the expence of extra msgpack
packing/unpacking. Hopefully this is a good tradeoff.

Ideally the entire cache should be replaced with a radix tree
but that will have to wait a bit.
