I've only lightly tested this so far, but this version adds an 
'eww-before-browse-function' option which lets you customize how EWW 
manipulates history before browsing to a new page. I've added functions 
for the default behavior ('eww-clear-future-history'), and for cloning 
all the "parent" entries ('eww-clone-previous-history')[1]. You can also 
set it to 'ignore', which will just preserve the old entries and add the 
new page to the end (which is the behavior v1 of my patch had).

I've also added more regression tests to make sure this all works as 
expected.

How does this look?
