The dispersion model GUI window is now set to a reasonable size for most screens.
The scrolled panel now allows all contents to be shown while having the window smaller than its
contents. The height of 750 pixels should be visible on the majority of computer monitors.
According to Google Analytics, ~13% of visits to http://www.nmr-relax.com have screen resolutions of
1366x768, therefore the dispersion model list window should now not be bigger than their screens.
