create windows exe and file type

[GoogleCodeExporter]

This has two components to this task:

1. Create a wrapped EXE which can be easily launched from Windows. Possible
alternatives include launch4j, jstub, and winrun4j. launch4j looks the most
promising.

2. Create an installer which registers file type associations in the
registry. r1114 adds SETUP.BAT which does the file type associations but
not the icons.
http://java.sun.com/developer/technicalArticles/J2SE/Desktop/jdic_assoc/
would let us set the file type associations from Java the first time the
program is run.

The benefits of this task are public perception rather than technical. This
would make it slightly easier for Windows users to try Orc, and increase
branding by attaching our icon/logo to Orc scripts.
