Feature c/browser rework update

Closes #2462

See merge request !541

This reverts commit a326ef62.

-keep a copy of the content of all clone's div inside the view data
-updateDivContent(divName,newContent) will check if the newContent is different from what we have stored before accessing the DOM for nothing

compute_size() should not have to check the dom to find the current div_size, it's the job of resize to keep this value up to date

not realy usefull for benchmarking asynchronous update

functionnal tests are working but not yet consistently

build and deploy doc
