Customizable GUI

[RoinujNosde]

Example config:

title: "gui.main.title"
rows: 3
components:
  leaderboard:
    slot: 3
    material: PAINTING
  panels:
    slots: [0, 1, 2, 3, 4, 5, 6, 7, 8]
    material: GRAY_STAINED_GLASS_PANE

To do:

• Enable/disable components
• Decorator components instead of panels?
• Update XMaterial
• Test config path for custom frames
• Fix Exception if default components are not in the config

It probably doesn't make to call InventoryDrawer.open() (and put it in the listeners map consequently) if getParent() is 'null'.

[RoinujNosde]

getParent() may or may not return null; also InventoryDrawer checks for null.
