[Paraview-developers] Buildbots migrated to Qt5

[Ben Boeckel]

Hi all,

Nearly all of the dashboards which test the GUI are now testing Qt5
(ista and bigmac are the exceptions). Since lots of builder names were
changing anyways, we took the chance to change builders from:

    +opengl2 -> nothing (assumed)
    +qt5 -> nothing (assumed)

and builders doing either the old OpenGL backend or Qt4 now explicitly
have:

    +opengl1
    +qt4

in their build names.
