Fix Docco TOC comment link

1.2.0 version bump

Merge remote-tracking branch 'origin/master'

Conflicts:
	_scripts/ugui.js

Upgrade Slider library, remove video, update imgs

The Bootstrap Slider library needed updating to handle logarithmic
ranges. Gave up on embedding video, there's no need to include a media
folder and video in every copy, just link to the site. Youtube embedding
isn't reliable enough without packaging custom NW.js with UGUI.

Bug Fixes - Multiple EZDZs, loading folder location

There was a bug where you couldn't have more than one EZDZ drag and drop
box without them conflicting. That's resolved and I also threw in a
traditional select dropdown. There was a bug where loading a saved
folder for a browse box returned undefined. Fixed.

Folder Browser added

Since selecting a folder is an important part of desktop apps, and it is
unique to NW.js over Chromium, I added it in to the page. UGUI now
handles processing, saving, and loading these input types.

Added Docco link to README

Version 1.0.0!

Spellcheck on comments. Added in file system functions like read and
