Subject: [PATCH] fix: resolve perf issue with a lot of forms

The property `response.forms` takes time (about 1.6 seconds) on an HTML
response containing a lot of froms (more than 30). For each form, the
whole reponse is parsed. To avoid reparsing all the HTML, I added a
cache on the property `Response.html` that parse the response.
