Enabled settings flag clicks to work.

A listener can be added to a flag. This listener is the same as a panel
item listener. When the settings flag is clicked, it'll call the
listener. There is a default listener. Right now the default is called
UpDownClick.java. This makes the rank go up when you left click and down
when you right click. Another implementation may be to just have the
rank loop around with left clicks.

I added two more ranks - Admin and Mod. These are special ranks that
have a value above owner. If a player is given this rank, they can
bypass protections. This will avoid the need to use permissions and also
enable islands to be set up that for example, only Admins can edit, but
Mods cannot.

So, it's now possible for an owner to lock out team members from the
island as well as visitors. This is a bit weird and so more click
classes should be created. For example, one that just toggles between
Owner and Visitor.

Currently, only an island owner can change settings, but this could be
expanded to allow members. Also, it will need to be expanded to allow
Admins.
