Fixes include:

- setting DEFAULT_STACK_TRACE=OFF for all release builds (prevents boost weak_ptr crash on some Linux systems)
- setting RPC-SSL to disabled by default (fixes "no connection to daemon" error)
- updated BlockchainLMDB::get_circulating_supply() to report staked coins as something other than BURNT
- bumped to v0.4.5
