• Fixes Bold / Italic / Strike / Underline buttons don't work correctly #19
• Problem: addRange or removeAllRanges kills the browser command states.
• Store cache in commandCache
• Add updateCommandCache and restoreCommandCache methods
• Add support for command-with-arg buttons to be in an active state
• Update command cache when running execCommand
• Store and then update selected commands when selecting a toolbar button
• Create the command cache by looking up the buttons that are in the DOM, set the default value to false

The cache doesn't work properly. See http://jsfiddle.net/mreq/6h8pw/1/ for an example. Try selecting a word and clicking bold and italic afterwards. The word is italic only as the boldness is somehow overriden. With the original file, the example works fine - http://jsfiddle.net/mreq/6h8pw/.

Commenting out everything connected with caching fixes that.

Hey @mreq, seems to have to do with using <a> tags for the data-edit commands. I'll take a look at why this is.
