* Renamed hbsg to generate_boot_screen and moved it to src/tools.

* Build generate_boot_screen as a build platform tool. It requires
  libpng to be installed.
* Added output file name as fourth argument.
* Replaced unnecessarily complicated
  fwrite(<string>, strlen(<string>),...) and sprintf()+fwrite()
  constructs by fputs() and fprintf() respectively.
