Make the folder-finding work remotely
Make it work @homeoffice on slslc and x02da-cons-2

At home, we mount the drives over MacFusion, the path to the images is
thus different.
Additionally, make it work on the SLS login cluster and the beamline
console 2.
Some whitespace changes due to PyCharm reformatting of the files
Renamed DisplayExperiment to GainDisplay, since that's what it does...

Also reformatting code with PyCharm
White space changes
Display *all* first experiments from the x-ray lab
Give correct title and display with good gray values

All experiments are shown with a descriptive title and displayed with a gray value max of ImageMean + 3 x ImageStandardDeviation.
Make work if HomeOffice=True and display STD, too

The standard deviation of the images is also informative.
pep8 this thing!
