graydon/rust — Issue #1348: "char": add a category function

Haskell implements a "GeneralCategory" and a function "Char -> GeneralCategory" to implement its Char-functions.
See e.g. http://haskell.org/ghc/docs/6.12.2/html/libraries/base-4.2.0.1/src/Data-Char.html

This would make it easier to implement additional, efficient functionality in Rust's "char" module. See #1347
