Commit FS#9467 - initial work on port to Sansa Clip by Rafaël Carré and François Dinel. A few cosmetic changes were made by me prior to committing: 1) TAB policing in button-clip.c; 2) Add François Dinel to CREDITS; 3) Add François Dinel as (C) holder in button-target.h (it was previously blank); 4) Add Rockbox header to bootloader/sansa_as3525.c with Rafaël Carré as (C) holder; 5) Change target_id to 50 (next available number) in tools/configure and fixed indentation; 6) Change MODEL_NUMBER in config-clip.h to 50 (next available number); 7) Remove unused in/out macros from system-target.h
