entities: support ' entity

The XHTML standard encompasses the XML standard.

From the beginning, the XML standard [1] has always included required
support for five character entities:

 1. the ampersand (&) as &
 2. the left angle bracket (<) as &lt;
 3. the right angle bracket (>) as &gt;
 4. the double-quote character (") as &quot;
 5. the apostrophe or single-quote character (') as &apos;

See section "2.4 Character Data and Markup" of the XML standard [1]
for further details.

Add support for the character single-quote character entity (&apos;)
in order to fully support XHTML pages.
