Refactored the source code now that it works

Should now compile across platforms. Makefile still absent but now supports command line options. This refactoring is designed to handle memory a bit better and will dispose of things it previously didn't. It also handles SIGINT and SIGTERM to properly flush the pcap files to disk and free all remaining memory.
