Feature/never ending UI tweaks 2 (#377)

* Using a rem based measurement rather than pixels, to better handle 4k displays and their adjusted font sizes - and setting relatively large breakpoints and page width limits that should result in a better view of the tables on the home page.

* Here is the latest:

    * Improved metadata display on the process instance page, with better widths, grayed out text (which I lost at some point).
    * Reduced the End Task "instructions for end user" size, and added a fade out on the bottom.
    * Improved the "chicken buttons" for custom columns on the process instance list filters, which can now accommodate very long names for the columns.
    * Removed the "show-page" which is more consistently handled by the content wrappers for the different routers.
