New image gallery functions

i've enabled a new set of image modules, that make it easier to upload and link images inside posts and comments. The 'camera' icon in the bar above the message body, starts the process and the steps are pretty intuitive.

the 'tree / stamp' icon still lets you easily link images into your post that are already present on the web somewhere.

as a bonus, we now have an 'image gallery' functionality, that clusters all of the images uploaded to the site. if you're the kind of person who'd like to keep a photo blog, try the contribute / image function.

let me know what you think -- and if it works as it should for you!
