Added protocol

Use a protocol defined in `README.md` and `chatty.h` for sending
messages.

Another big change is the clientsArena which now stores metadata for the
connection such as the author's name.

Misc:
- Merged arena.h and common.h into chatty.h
    - removed all the unused code from arena.h as it was not very
      useful and would not win me any time.
- Added compile_flag.txt
- Changed formatting
- Added more log messages
- Added more asserts
- Added bool type via enum
