Big update to imageRecorder

Very much has changed since last version. That's why I didn't overwrite
the old one. Also didnt know how to create a new branch without messing
everything up so I just uploaded it into the folder imagerecorder2.

- Changed the way uploaded images is being stored and handled.
- User is asked to enter library name @ start (issue #192)
- AJAX Upload function, image is uploaded once selected. (issue #193)
- Some graphical changes (should solve issue #199)
- Separated PHP Upload file.
- Imagenames gets encrypted to avoid conflicts (issue #192)
- Possible to switch between images (issue #197)

To be able to play the new librarys simply move the unique library
folder to /canvasrenderer/ and change the XML-load to
libraryname/data.xml.
