[nRF51822] Change image generation mechanism

- The final image is now generated at "binary" step, which is compatible with
  the on-line build system structure
- The SoftDevice image is appended to the application code, resulting in a
  single .hex image file
- Python is used for merging and generating .hex files using the 'intelhex'
  module, no more dependencies on external tools
