fix GRC files: own filename.py, solved Range input conversion incompatibility

[marcusmueller]

• replaces top_block.py as the name with which python files are generated from GRCs by the GRC files' name minus .grc.
• Tidies up the FSK single target tracking flow graph
• There was a problem where the Range sliders led to unconvertable GRC files; fixed that by renaming them and giving them range as label

hi, is gr-radar support hackrf-one ? I want to test OFDM waveform in hackrf-one and want to start with KIT's gr-radar.

@liubenyuan : This is not the place to discuss things like that; however, gr-radar is a generally usable radar framework; it should work with any hardware that can offer coherent RX and TX channels. I don't know whether the HackRF does that. I recommend signing up for the discuss-gnuradio mailing list, introducing what you want to do there shortly and asking your question.
