Update:

* HeadDatabase hook has now been implemented, so all GUI Menus can now have HeadDatabase icons or Materials.

To use a HDB icon use `hdb-34567
This however does not include the menu fillers

* Icons in the Plot Management menu can now be changed, which I appeared to have miss on the first implementation of changeable icons.

* General code tidy-up so easier to read

* A Permission check has been added when the `add player rank` icon is clicked. The permission is the Towny rank permission.

I would like to thank IRules and MyNameIsAres for their help with the HeadDatabase integration.
