LUA code correction - findNearestItem()

Bugs
1

The code should read:

local item = self:findNearestItem()
if item then
    -- Move to the position of the item.
    local pos = item.pos
    local x = pos.x
    local y = pos.y
    self:moveXY(x,y)
end

Where would one submit a patch for the help included with Thangs ?

Functions are also undocumented. I could write documentation based on what works in game and what the manuals are saying about functions if I knew where to add the definition.
