Edward Z. Yang bf0d659c47 [2.0.1] Improve special case handling for <script>
- DirectLex now honors comments with greater than or less than signs in them
- Comments are transformed into script elements, ending comments are scrapped
- Buggy generator code rewritten to be more error-proof
- AttrValidator checks if token has attributes before processing
- Remove invalid documentation from Scripting
- "Commenting" of script elements switched to the more advanced version
