Improved spc_fork to remove all bugs (take that cookbook!). Split out code from sdllink to a seperate file. Added a safe popen() which doesn't return until it knows the application is there or not, and doesn't carry around extra data, can be closed with fclose(). Fixed some warnings. And there was much rejoicing across the land.
