Minor update to bugs.html

This commit changes inc/md2html.cfg also and it is done to make the
header (under the line 'The International Obfuscated C Code Contest')
match the header in the bugs.md file, in case. Updating bugs.md is not
necessary. A keyword was also added to the html file, mis-features,
along with the already existing misfeatures.
