Issue Description:

I'm trying to use custom functions to wrap up IRecipeAction and IRecipeFunction to make it looks better, but the problem came when I tried to pass string argument to player.hasGameStage and player.addGameStage which provided by GameStages.

What happens:

Type 'crafttweaker/api/player/IPlayer' (current frame, stack[1]) is not assignable to 'java/lang/String'

What you expected to happen:

The string argument should be passed to these two methods correctly like when I use a "" string
