import: Use html.parser instead of lxml in bs4.

lxml parser appends html and body tags to the soup object which
are not reqired. There are no other major parsing diffrences between
the two parsers as long the HTML input is perfectly formated.
lxml parser is much faster than html.parser but it hardly matters
in our case.
