Allow Mac users to double-click to launch Crawl:

- Use argv[0] to figure out where Crawl lives and where to find data files.
  The Mac Finder sets the working directory to / and the full path to the 
  executable is available in argv[0] when the user double-clicks.
- Converted some of the old char*s to std::string.
