WARNING: Currently, this is only fully supported in non IE browsers.
How to use it:
Select the options below as you want them to be by default.
Enter the "SourceUrl" where you placed the source data which you find under build/textarea/src (you can also leave the default to server the scripts from GitHub).
Click the "Build Link" button to generate your custom Ace Bookmarklet.
Drag the generated link to your toolbar or store it somewhere else.
Go to a page with an textarea element and click the bookmarklet - wait a little bit till the files are loaded.
Click 3 times on the textarea you want to replace - Ace will replace it.
To change settings, just click the red icon in the bottom right corner.
