Packaged code under net.sf.jse rather than the default package.
Created a JSE Ant task for expanding macros into source code.
Created an Ant build file to build the whole JSE distribution. This replaces the previous make file, and the Jscheme alternative, which are no longer included in the distribution.
Created a JSE jar file (and an simple mechanism to install with Ant) for ease of development.
Replaced SpecialClassLoader with SpecialIntanceLoader, since it wasn't really a java.lang.ClassLoader that was needed. In the process this change fixed the limitation that SpecialClassLoader could only load classes from the filesystem, not from jars.
