Externalized sql query for Bloomfilters, Introduced NoDefBinaryConversion

- The new externalized sql query handling a Bloomfilter allows a developer to determine which packets should be tested against an incomming Bloomfilter.
- The NoDefBinaryConversion allows a developer to extend a conversion object which does not define all default Dispersy messages. Usefull when you want to only define a couple messages in a conversion object and let other conversion classes to overwrite any of the default Dispersy messages.
