Placeholder for /tpauto and /msgtoggle

[MadPanCake]

Feature description

Placeholders that say:

• If the player has '/tpauto' command enabled
• If the player '/msgtoggle' enabled
  These placeholders return: 'true' or 'false'.

How the feature is useful

• These placeholders provide feedback and increase the interactivity on servers.
• An example of this is a: settings menu, profile menu, in which we will be able to not just blindly toggle those 2 settings, but also to see what's the current state, and react accordingly.
• There are already similar placeholders implemented. So this would also increase the parity.
• Placeholders are generally increasing the plugins' usefulness and universality, by letting knowledgeable server admins create a more fun experience for the players, which, after all, is the ultimate goal of the whole thing :)
