Subject: [PATCH] Make sure that Ajax form submissions (both get and post)
 always make a new request, even if it's identical to a previous submission.
 When a duplicate cached result page is present, it'll be removed from the DOM
 after the page change is complete . Thanks @medovob for the ideas and feature
 request. Fixes #368, Fixes #366
