patch by Artur Wyszynski (aljen):

* Added the feature of an animated boot screen (icons lighting up at
  different boot stages).
* Added first version of new boot splash images, generated by the new
  hsbg tool. (Also finally contains the "new" Haiku logo.)

changes by myself:
* Added Artur to the contributors list in About System.
* Fixed some left overs in the patch, kept tracing turned off.

TODO:
* Remove the need for hard coding the icon positions. (Maybe generate
  those from hsbg and put them into images.h? Have user provide icon
  spacing/offsets at the command line for hsbg?)
* Rename the stages to something meaningful.
* Use hsbg as a build system tool and generate images.h during build
  from PNGs provided in the artwork folder.
