Remove sprite

Merged username-removed-92236 requested to merge remove_sprite into master

Fixes #253 (closed)

in this commit:

  • swapped IBM & CERN logos
  • sprite was removed, in favor of loading individual images. the reasoning behind this is due to future support (i.e. due to the necessity to change company logos, the future person may find it tedious to do lots of work in creating a new sprite, only to have to change one logo)
  • remove border lines
  • sized up images to the best of my ability
  • increased opacity because the header needs to stand out as much as possible and it doesn't when all the logos are the same color
