* Tracked down the mkdepend tool which Ingo used in his updated makefile-engine

which auto-generates dependencies. It was written by Lars Duening for BeOS
  and uses libglob, which is also part of make. To re-use libglob and since
  make is already part of the Haiku tree, I added mkdepend to the bin tools.
* Added Lars Duening's copyright to AboutSystem.
* Added skeleton makefile and makefile-engine to data/develop.
* Added mkdepend and makefile-engine files to the Development optional package.
  It could be argued to move the make bin command there too, from it's current
  location in the HaikuImage file. However, make could be useful to always
  have available.
