bespin nodejs tasks

0. (bootstrap) write bash script to download and install nodejs and dependency addons:
    node-jake for now. (using npm with version number of each addon)
    (it could be based on nDistro)
    The idea is to create a bespin-dependencies package and register it with npm.
    This package will contain specific versions of:
    jsdoc, closure-compiler, tiki, core_test and jquery.

1. write tests for Jakefile tasks using core_test
2. write Jakefile
   a. implement dist task.
      Given that the bootstrap already downloaded dependencies then we can:
      aa. combine js, css
      aaa. compile source (using closure-compiler)
      aaaa. compress js, css
      aaaaa. run doc task
      aaaaaa. create distributable version of bespin for titanium, xulrunner,
             adobe air, etc.
             with precompiled nodejs for linux, unix and windows. (32, 64 bits)
   b. implement start task: launch (browser|titanium|xulrunner|adobe air) with bespin
   c. implement test task to run jakefile tests, server and client tests
   d. implement doc tasks

3. rewrite plugins/boot/bespin/plugins.js to support the same plugin system
   in both, client and server.
