Re"factor" to always run analysis from AFS

- Get git hash only once per run
- Decide if the image should be looked at, after the decision to redo
  the analysis has been taken
- Optimize display and tiles of figures
Only animate if we want to

And - since Keynote doesn't seem to honor transparency in movies anymore
- also write the frames of the movie as images with non-transparent
  background.
Display images based on a sorting criterion

We can select to display based on a criterion.
Show the images only sorted, don't bother showing them unsorted in the
row above.
Randomly select some images from the whole bunch

We randomly select some image from the 2000 that Ivan made, sort them by
either STD, mean or ID and present them in a figure.
Like that we can hopefully weed out the unnecessary ones and get to the
core of the result
Nicely animate plots (Progress Report 09/14)

Using http://git.io/HnaW9A as help, we animate the plots, which makes
them 'nice' for the progress report.
This is much nicer than to just write out the movie frames as individual
png files...
