Creates ntcoin to set up relevant directories, scripts, and binaries for tcoin and pcoin

1. Sets up all relevant directories, scripts and binaries for tcoin and pcoin, assuming the current directory is right inside the GitHub repo (same depth as the LICENSE file).

2. Creates soft-links to the executables in "bin" folder inside the "tcoin" folder in the "~/bin" folder.

3. Prints the relevant preprocessor directives to be put in tcoin.cpp and pcoin.cpp (without actually putting it in those two files).

Because of 3. above, the tcoin.cpp and pcoin.cpp files will have to be modified again, after which "compile_tcoin" and "compile_pcoin" can be called again to update the binaries.
