info about web browser extensions wikified

Since I'm going to be giving a presentation on web browser extensions for libraries, I should have some good resources for y'all.  Fortunately Gianluca Drago already beat me to it by building an extensive page, that runs on a home machine.

I proposed and Gianluca agreed to move this content to a more permanent wiki home where everyone can contribute to extending it.  I have started moving some of the links over to

Lib Success Wiki - Technology - Web Browser Extensions

Please feel free to add to that page.
