document more internals, based on mailing list discussion
...
this should address #27 , #28 and #29 at least at a basic level
it is mostly based on the mailing list discussion mentionned in #27 ,
with some reformatting and merging of different posts.

document key files in a new Internals page
...
this is still incomplete as it only describes key files, but doesn't
clearly say how chunks are encrypted or decrypted.
this address parts of #29 but eventually that document should also
cover #27 , #28 and maybe #45

at least until the original permissions are set.

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

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.
