Issue Description:

Client-side and server-side does not syncronize for addTooltip and addShiftTooltip.

What happens:

The client-side item does not show §6Hello! when writing 'minecraft:iron_sword.addTooltip("§6Hello！");' in 'scriptsin the server-side. I would have to write '<minecraft:iron_sword>.addTooltip("§6Hello！");' in the client side for it to show up. The same happens foraddShiftTooltip`.

What you expected to happen:

The client side will display '§6Hello!' if 'minecraft:iron_sword.addTooltip("§6Hello！");' or 'minecraft:iron_sword.addShiftTooltip("§6Hello！");'
is set in the server side 'scripts'.

You need the same scripts on both server and client.
No scripts are synchronized between client and server.

Older versions can be synchronized

Will synchronization between client and server be added later?

Most likely not in 1.12.

Recipes can no longer be synchronized due to a change in MC.
Reloading was the main cause of issues in the MT/CrT GH repository due to caching and it drastically increased server join time. (In some larger packs you couldnt even join the server cause you timed out before you received all the CrT scripts from the server)
