Adding noder preprocessors for the compiler and the transpiler.

Here is a sample noder configuration which uses the transpiler
and the compiler preprocessors. Patterns can be adapted to select
which files will be processed by the compiler or the transpiler:

{
 packaging: {
  preprocessors: [{
   pattern : /\.hsp$/,
   module: "hsp/compiler/compile"
  }, {
   pattern : /\.(hsp|js)$/,
   module: "hsp/transpiler/transpile"
  }]
}

The compiler noder client-side package now also includes the
transpiler and uglify-js.
