* Make compatible with the current Crypto++ master
* Add auto-config and build script. Not important, just a time-saver.
* Address compatibility with Crypto++ 6.0 release, while maintaining compatibility
with the older Crypto++ releases.
* Polish comments in cryptopp_byte.h. Forgot to include it to RandomGeneratorThread - fixed.
* Late at night - forgot to fix the .cpp files that used ::byte...
* Renamed auto-config-and-run script
* Added comments/description, and commented out "make check" that fails anyway
* Changed the include guard to match the rest of the .h files
* Delete build script
* Update ChangeLog.txt

Performance optimization: When removing or shrinking a tree, we don't load/read leaves anymore. Loading inner nodes is enough to get all block IDs and then we can delete the leaves from their IDs without loading them.

ClientId is not loaded/generated inside of KnownBlockVersions, but in CryDevice. This way, CryDevice also has access to the ClientID. This is later needed to recognize whether we're in a single-client or in a multi-client setting.

VersionCountingBlockStore is initialized with a flag, saying whether missing blocks are integrity errors. This flag is meant to be activated in a single-client scenario to have this additional integrity check.

Deleting a block doesn't set the version number to MAX_UINT64, but just increases it by one. This makes sure, that if (in case of a synchronization conflict) the block is reintroduced by another client, this is accepted.

When increasing the version number, don't only look at the version number in the block, but also at the last version number given to it by the current client. Ensure, the new version number is higher than both.

Ciphertext blocks are split into subdirectories (before, all were on top level) to reduce number of files per directory. Some unix tools don't work well with directories with too many entries.
