This update adds a new Button state life-cycle to make it easier to prepare data before rendering and a new forceSyncUpdate to force a GUI to be updated in sync.
When forcedSyncUpdate is enabled it will also update sync even if you use the onUpdateAsync().


Changelog

• Added ButtonPrepareRender method, which makes it easier to prepare data for render. (commit: 3ab90d0)
• Implemented prepareRender method in ActionButton, ItemInputButton, etc. (commit: 01039ed)
• Added forceSyncUpdate option to GuiWindow. (This option forces any updates, also async render, to be executed in sync. This should be used when using ItemInputButtons to prevent item duplication!) (commit: 12ff065)
• Added explanation to the render method (commit: 1621e18)
