Add more information to error messages in mw.html. This includes the error level, the function name, and the position of the argument in the argument list. Where possible, use the functions in libraryUtil.lua to do this. Some functions in mw.html accept multiple types, so add a checkTypeMulti function to libraryUtil.lua to make these kinds of functions easy to check. And while we're at it, add test cases for libraryUtil.lua as well. Change-Id: If9cf9a52bd4b1bb42cc7f9f1f1096828710cbc52
