"/patterns hex" command doesn't hide stroke order for great spells

[Robotgiggle]

When you show a great spell using /pattern name, the stroke order is hidden since there's no way to know the correct order for your specific world. However, when using /patterns hex, this does not happen. Great spells are displayed using the "default" stroke order, which is almost certainly not correct for the user running the command.

Here's an example. The pattern for Greater Teleport should be using the solid purple arrowless version like with /pattern name.

Should also make it possible to specify other patterns to be drawn without arrows
