Resolve aliases in cost calculation (#175) 

If stairs from stairs mod were crafted before moreblocks was enabled, the old (now aliased) stairs variant is kept in inventory. If the player tried to recycle that stair variant, `inv:contains_item("output", stackname)` would return true as `contains_item` resolves alias names, but `circular_saw:get_cost` would return nil as it's expecting exact `stackname` matches which would later crash due to nil arithmetic.

This PR fixes this issue by resolving alias using `minetest.registered_aliases` table.
`circular_saw:get_cost` should work now in every scenario where `inv:contains_item("output", stackname)` returns true.
