Add useful tools to images in WYSIWYG editor

[smagnusson]

In running silverstripe.com, I often find myself wasting plenty of time going into the Files and Images area, when I could just do something in the Content Editor. The main things I need to do are;

1. cropping and rotating images 2. renaming images 3. deleting images

See the attached screenshot for how I feel this could work. Right clicking on an image would either a) Bring up Mateuz's wonderful image editor. Note that this edits the existing file, so you might want to b) Make a copy of the existing image, so that you can one one which is uncropped, and one that is cropped, etc. c) Rename the file d) Delete it, for house keeping

Secondly, when you right click an image ALREADY IN THE EDITOR, have the 'image editor' as one of the options.

This means people will make use of the awesome interface!

Mateusz, this isn't urgent but it would be great if you could submit a patch for this if you had some free time at some stage.

We've waited a year for matuesz to do this so I say it gets done in house :)

There's a separate ticket that talks about making the image editing service used changeable with a plug-in. We'd just need to ensure that this feature also talks to the plug-in in the same way as the Files & Images section editor.
