Proper PDCurses/Windows support and some other stuff

* Added PDCurses support. Consequently, Windows is properly supported now
* Use map.find instead map.at when parsing command line options (because I was an idiot and forgot that try doesn't catch out of range exceptions)
* Fixed the options parser for asciiplay
* Updated README
