boot.js without webpack overhead
Modified Jua.js to be without jQuery

Replaced ifvisible.js with simple drop-in replacement
Replaced momentToNode with proper HTML5

The Squire implementation is not 100% compatible yet, but it shows the massive overhead of CKEditor.

Still TODO:

	normal	min	gzip	min gzip
squire	128.826	47.074	33.671	15.596
ckeditor	?	520.035	?	155.916

CKEditor including the 7 asset requests (css,language,plugins,icons) is 633.46 KB / 180.47 KB (gzip).

To use the old CKEditor, you must install the plugin.
