Bump CC:T to 1.103.0

- Bump Cobalt to 0.6.0. We now track both line and column numbers of
   each bytecode instruction, allowing us to map an error to a concrete
   position.

 - `loadfile` (and similar functions) now use the full path, rather than
   the file name. Cobalt truncates this to 30 characters (rather than
   the previous 60) so this should be less noisy.

 - The shell, edit and Lua REPL now display the corresponding source
   code alongside an error.

   Note this is incredibly limited right now - it won't cope with errors
   which cross coroutine boundaries. Supporting this is on the roadmap,
   but requires some careful API design.
