Special QADComponent for Invoke's

[Longor1996]

So the idea here is to, basically, take all the code from talecraft/client/gui/invoke/InvokePanelBuilder.java and turn it into a single self-contained QADInvokeComponent, instead of creating a bunch of separate components. This should make the data-binding simpler. Also, opens up the possibility to add more kinds of Invokes more easily.

• Create a special QADComponent for Invoke instances, internally consisting of a set of small components...
  • The component must reflect the NBT compound that represents a Invoke.
  • The GUI must not need to reload to reflect changing the Invoke type.
  • A drop-down button (or similar) for selection of Invoke-type.
  • Depending on Invoke type, different sets of input (which are synced on GUI close):
    • Null-Invoke: Doesn't need any input.
    • Blocktrigger-Invoke: A button to set the affected region and a toggle-button for the trigger-type.
    • Command-Invoke: A text-field.
    • Embedded-Script-Invoke: A text-field.
    • File-Script-Invoke: A text-field.
  • A button to 'execute' the invoke (for testing), using the clients current (possibly modified) NBT data for the Invoke.
  • A 'cancel' button to throw away any changes made to the invoke.
• Replace all uses of InvokePanelBuilder with the new component.
• Make sure all future uses of Invoke's go trough the new component.
