feature: adds plugin interface, webdriver support

[r1b]

PhantomJS chokes on a lot of SSL pages I want to monitor so I added a plugin interface and a webdriver plugin.

I think some of my semantics are still slightly off (e.g: currently doing full-page screenshot instead of respecting resolutions) - I will fix these shortly.

Wanted to see if this was something you were interested in.

This is very interesting! I actually thought about doing something similar just recently. We definitely need to move away from PhantomJS.

I wrote a couple of modules in preparation already too:

• https://github.com/juliangruber/capture-chrome
• https://github.com/juliangruber/capture-firefox
• https://github.com/juliangruber/capture-electron
• https://github.com/juliangruber/capture-phantomjs

Those use command line interfaces instead of Webdriver. I wasn't sure about using it, do you see any strong points in favor of Webdriver?

I'll collect my thoughts on this PR in another comment, don't think I forgot about it.

About the missing cut option, I thought about dropping it anyway in favor of a client side fold overlay. What do you think about that?

Hi Julian,

I like these capture modules better since they don't require any prerequisite setup or a running selenium server.

re: cut - client side overlay is fine, it is also easily done as post processing - will you be able to toggle the overlay in the UI?

that's the plan :) i want to overhaul the UI anyways

awesome - when i get a chance this week i will update this PR (or maybe just make a new one) that:

1. Uses these modules you have created as plugins
2. Restores your resolution semantics and ensures a full-page screenshot option is available for all plugins

Awesome, thank you so much!
