Online edit of images

[sonalkr132]

Users should be able to edit any image they have uploaded to us. It should support basic functionality needed for last minute tweaks.
We have tried previously to introduce this feature however it is not in working state. We can use following projects to have a fresh stab at it:

• http://sourceforge.net/projects/akoie/
• https://github.com/jseidelin/pixastic
• https://github.com/zefei/picmagick
• https://developers.aviary.com/docs/web
