--[[
	This function registers the nodes and craft rezieps for the reinforce stuff
	 * name: String which is used in description and as technical name (lower letters)
	 * craftItem: the Item where the reinforce is crafted out of
	 * nodedef: Nodedefinition table as used as in minetest.register_node()

	The Nodes are caled
	<modname>:reinforced_<name>
	<modname>:reinforced_<name>_slope
	<modname>:reinforced_<name>_arrow
	<modname>:reinforced_<name>_bars

	The modname is automatically the mod that currently calls this function. 
	e.g. if you call darkage.register_reinforce from the mod medieval modname will be medieval
