Tidy up changes from LV2r3.
Remove references to nonexistent lv2:float. Update version to conform to new definition. Update date. Simplify obtuse language about properties ("with object"). Remove redundant description of mandatory port properties. Require lv2:binary to be present in manifest.ttl. Generic description of lv2:minimum and lv2:maximum.
