Fix game logic coordinate system

Prior to this patch, the game used this coordinate system for
moving ships around and whatnot

             270 degrees   +z
                      -y    ^
                       \    |
                        \   |
                         \  |
                          \ |
 180 degrees               \|
   -x <---------------------\------------------------> +x   0 degrees
                            |\
                            | \
                            |  \
                            |   \
                            |    \
                            v     +y
                           -z      90 degrees

After this patch, it uses this system

             270 degrees    +y
                      -z    ^
                       \    |
                        \   |
                         \  |
                          \ |
 180 degrees               \|
   -x <---------------------\------------------------> +x   0 degrees
                            |\
                            | \
                            |  \
                            |   \
                            |    \
                            v     +z
                           -y      90 degrees

Given (x,y,z) in old coords, new coords (x',y',z') == (x, z, y);

Just swap y and z, and negate sin() (he says, as if it were just that easy).
Add debugging info to 3d displays
adjust models for coordinate system

                      -z    ^
                       \    |
                        \   |
                         \  |
                          \ |
                           \|
   -x <---------------------\------------------------> +x
                            |\
                            | \
                            |  \
                            |   \
                            |    \
                            v     +z
                           -y
