Added my own Gzip Filter for Botan. All classes now use that instead
of the patched Zlib version.
Bumped router version.
Refactored BuildRecord classes (removed PK_*_Filter dependence).
Refactored EstablishmentState (removed PK_*_Filter dependence).
Refactored RouterInfo (removed PK_*_Filter dependence).
Declared virtual dtors explicitly instead of setting them to default
(h/t EinMByte).
Removed getType() from the Handlers.
Made StaticByteArray's template parameter more accurate.
Updated TODO.
Updated README.md.
Deleted the Botan patch as it is no longer needed.
Fixed a small bug in the TunnelGateway and DatabaseStore parsing code.
