Updated ckeditor buttons, plugins, and layout

Grabbed latest version of ckeditor 4.
Changed the source plugin to work with CodeMirror plugin
Dumped font-awesome and bootstrap icons. They are buggy in Chrome and our users wouldn't probably get much use.
Removed all the indent code. Not needed with CodeMirror.
phpws_config is using default toolbar settings with icons removed. CodeMirror settings have been added as well. Most are default but leaving in should someone want to change them.
