Title: Added 'exclude' option to PageMod.

Added optional 'exclude' option to PageMod. If option is undefined, has same behavior as before. Otherwise, option must be a string, regexp, or non-empty array of strings and regexps. Then, a URL is matched if it matches the PageMod's 'include' AND does not match its 'exclude'.
