utf8 egg: Missing character type predicates

Estimated difficulty: easy

Description

The utf8 egg doesn't provide Unicode-aware versions of the R5RS character type predicates (char-whitespace?, etc.). The attached patch provides them; it is based on my updated version of the unicode-char-sets extension (see ​http://bugs.call-cc.org/ticket/1851). It can easily be modified to work with other versions of the egg by simply replacing the multiple char-set imports with (import (unicode-char-sets)).
