[vtkusers] vtk.org download page redesign

Hi Chris,

I like the slicer approach for displaying the current versions: large buttons in a matrix, with your current browser's OS highlighted. Unlike slicer and paraview, VTK is a library, so the source should probably also be featured as a big Bootstrap button. I like slicer's system requirements and think we should provide some information about what platforms undergo heavy testing.

I think that older versions should be available, like the ParaView page -- but they should not clutter the page with pull-down menus that you feel you must inspect before clicking the download button.

I think both slicer and paraview are missing release notes as a prominent feature. Finally, checksum information should be available, especially for source code.
