Implemented optimized sendtable parsing
Moved *all* protobuf dependencies behind SLOW_PROTOBUF
Removed unused Assembly references

Now the references no longer shout "VISUAL STUDIO" when you look at them
RIP protobuf-net

If someone really needs SLOW_PROTOBUF, they can just add the package.

DemoInfo is now fully compatible with mono-llvm (~20% faster).
»ESL One fnatic vs NiP on de_cache« just parsed in less than a second on my machine.
DemoInfo is fast. I'm pleased.
