Please read! Reorganization of files.

Best advise: Please freshly checkout the SRanger module.

Several dir-structure and file rearrangements and clean-ups were performed:

in FB_spmcontrol: separated DSP code from other support code, like py-scripts and watch-tools. Added new/different Makefiel to generate DSP code via Linux DSP CC tools from TI, check the info in the MakefileDSP and help phorum.

Moved the SR_Counter CPLD code one level down.
