New logging and more (#446)
- `TT_LOG_*` macros are replaced by `Logger` via `#include<Tactility/Logger.h>`
- Changed default timezone to Europe/Amsterdam
- Fix for logic bug in unPhone hardware
- Fix for init/deinit in DRV2605 driver
- Other fixes
- Removed optimization that broke unPhone (disabled the moving of heap-related functions to flash)
