  Log Message:
  -----------
  yocto: slides: overview: rework and extend the Lexicon, add pictures

Main goals:

 * introduce recipes _and tasks_ early in the training, as they are
   unavoidably mentioned soon later
   * add pictures to clarify them
 * explain the word "poky" and its overloads
 * rearrange some info about layers and oe-core
