From 1.0.10 to 1.0.11

• some new functions and contexts;
• name lookup is now more consistent. That is

     Dim Shared Name
     With Ships(1) Do Name := "USS " & Name

  does no longer read the ship name (right side) but assign to the global variable (left side). They now both refer to the ship name (which can't yet be assigned to);
• can print backtraces on error.
