- 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
1. rewrite of the Haven variation of the Pricing Record class to support:
- versioning of the PR format
- nested supply_data and asset_data structs
- verification of the signature using a variable-length string (not R+S)
2. calculation of the slippage tallies for a block in add_block(), so that
we can work out the yield that is due to be paid out for the block.
Loads of little fixes and cleanups.
