Release notes 0.5.2

The 0.5.2 release includes two essential patches

• Disk I/O is reduced by configuring LevelDB more efficiently (#1339)
• Set the payment-threshold field as a copy, instead of a reference (#1329)

There was one minor patch, making it possible for MacOS users who use brew to update their bee node (#1334)

Lastly, the deploy command was added to bee. This command deploys a chequebook if needed, thus reducing the time for the main service to start up and allowing bee to start in environments which have strict requirements on boot-up time (such as Windows) (#1314)
