v0.1.23

closes #266 

Couple of notes on this one:

* I have added the code command plugin to the examples, added the button and the keyboard shortcut `meta + shift + l` to trigger it - normally inline code would be `meta + shift + k` but that is currently in use for unlink as the opposite to the very common `meta + k` for links.
* I attempted to add the noting plugin, but it has an extra dependency on lodash and given the plugin has it's own example it seemed like it might be going too far.
* I noticed `scribe-plugin-formatter-html-ensure-semantic-elements` and `scribe-plugin-inline-styles-to-elements` are also not included in the example

If you'd like me to change any of the above (or anything else for that matter) let me know :)
