Added components (transistor and balun) for the uSD variant.

- atusd/Makefile:
- AUTHORS, atusd/Makefile, atusd/dtc123.lib, atusd/dtc123je.fpd: borrowed
  the DTC123 symbol (Alvaro Lopes) and footprint (Dave Ball) from
  gta02-core. Note that this isn't the part I'm using in my prototype, and
  I'm trying to get rid of it entirely, so all this will change before too
  long.
- components/BOOKSHELF, components/INFO, components/balun.lib,
  modules/Makefile, modules/INFO, modules/0805-6.fpd: added the Wuerth
  748421245 balun
