Add scripts folder

Add a 'simplified' build that's made of scripts/batches for BASH/windows. No dependency scan, just rebuilds every time. The scripts act as better examples, and simplify making compound builds composed of many FLA/mxmlc sub-projects that need to be exported/built in a particular order. The jsfl script works with Flash 8/CS3/CS4, but I'm still testing. The example runs when built with Flash 8 or Flash CS3, but not CS4/Flash 10, so I need to look at some of the security settings and sort that out.
