Squire vs CKEditor

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

Still TODO:

• support for tables (really needed?!?)
• support BIDI (really needed?!?)

	normal	min	gzip	min gzip
squire	122.321	41.906	31.867	14.330
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.
