Better Search and Modified Zoom

[linux-man]

Open/close with Control+Shift+f
Find words inside SPAN
Don't duplicate findings

Block dimension calculation is not accurate, so zoom is made on mouse coordinates
Change default modifier to ctrl - alt don't work on Linux
New parameter zoomLevel: default 2

Also, can you bless (or curse) the reveal.js editor I'm writing?

@hakimel what do you think?

Search improvements look great.

I don't want to remove the zooming based on element bounds, if it's not working correctly we should fix it instead. It's useful to be able to zoom specific elements rather than a point when you want to, for example, enlarge a whole code block.

How about adding the point zoom using a different shortcut than alt + click?

I turned to point-zoom because I couldn't fix the element zoom. The biggest problem is on fullscreen. Even when it's good on a maximized window, turning fullscreen send the elements to strange places. Maybe the issue is browser-dependent.

This has been merged into the dev branch 🙌

Played around with the point based zoom and I like how it's more predictable than element based zooming, since element bounds aren't always what you expect them to be.

ctrl + click brings up the context menu in OS X so I've made the shortcut platform dependent (ctrl for Linux, alt for all others).
