New commit pushed.  

Added:

• Configuration options to set MySQL server IP address and port
• Configuration option to set RPC timeout
• Instructions on how to set up an empty database from the command line

Fixed:

• Type errors when logging or sending messages to stderr. Exception descriptors are now always cast to string
• The database loader will now throw an exception when a block  height of "-1" is sent to the block parser instead of attempting to process it.
