Color

[ghowa]

Adds color as an additional means of visualisation and the possibility to show the original image with a click on the respective thumbnail

• For color visualisation, for each group (i.e. color) a new mesh is created and the images are then added to the respective meshes
• For displaying the original image, the corresponding image id is added to each face via the userData object

The "click on the thumbnail to get the original image" collides with #28, which uses clicking for URL-change to support bookmarking. Maybe the original image could be accessed via double click?

I just tested it on my local machine: Clicking on a thumbnail opens the original image in a new tab, and at the same time the URL in the original Pixplot tab is updated and can be used for bookmarking.
