Issue in 'tiledProperties(properties)' of ponyTiled code

[jcbk101]

If i create a custom property in Tiled map editor, and is a 'bool' property that is set to false, and the custom property entered is the first in the list, then the properties never get converted.

properties[1].value

local function tiledProperties(properties)	
	if (#properties > 0) and properties[1].name and properties[1].value  then
		...
	end
end

Here is a fix... (properties[1].value ~= nil)

local function tiledProperties(properties)	
	if (#properties > 0) and properties[1].name and (properties[1].value ~= nil)  then
		...
	end
end
