v2.0.2-rc (#27)

## v2.0.2-rc

### BREAKING CHANGES

* Refactored `config.json` - will need to verify configuration settings prior to mounting

### Issues

* \#12 \[Unit Test\] Complete all providers unit tests
* \#14 \[Unit Test\] SQLite mini-ORM unit tests and cleanup
* \#16 Add support for bucket name in Sia provider
* \#17 Update to common c++ build system
  * A single 64-bit Linux Jenkins server is used to build all Linux and Windows versions
  * All dependency sources are now included
  * MSVC is no longer supported
  * MSYS2 is required for building Windows binaries on Windows
  * OS X support is temporarily disabled
* \#19 \[bug\] Rename file is broken for files that are existing
* \#23 \[bug\] Incorrect file size displayed while upload is pending
* \#24 RocksDB implementations should be transactional
* \#25 Writes should block when maximum cache size is reached
* \#26 Complete ring buffer and direct download support

### Changes from v2.0.1-rc

* Ability to choose between RocksDB and SQLite databases
* Added direct reads and implemented download fallback
* Corrected file times on S3 and Sia providers
* Corrected handling of `chown()` and `chmod()`
* Fixed erroneous download of chunks after resize
