massive refactor; as much as possible, handle input and output unit in the same way; handle combinations (todo: ftin)
(fix default expressions so they do not use loadstring (not available in Scribunto))

-- Convert a value from one unit of measurement to another.
--[[
-- Example: {{convert|123|lb|kg}} --> 123 pounds (56 kg)
Later TODO Too many items to list, but following are some points:
- Some conversions require two outputs: {{convert|55|nmi|km mi}}.
- Some units have two values: {{convert|3.21|m|ftin}}.
- Some units use the plural name, not the symbol, example:
{{convert|12|ha}} --should give--> 12 hectares (30 acres)
