create Cakefile to do build and test tasks

[yyfearth]

Create a Cakafile including build and test tasks:

• build task: complete subtasks listed in https://github.com/yyfearth/madtalk/wiki/Build-Tasks
• test task: run all test cases in test/ dir
• build:full task (optional): build then test

Under Windows 7, the correct way to call external program to copy a directory is:

{exec} = require 'child_process'
exec 'robocopy source target /e', -> console.log 'okay'

@yyfearth Minifying current client.coffee takes around 5 seconds on my machine. I let it check whether the file exists or not. If yes, then ignore.

@yyfearth I couldn't successfully compile client.styl to css. It reported:

Object
...
 has no method 'replace'
    at Object.Lexer
...

Please test it on your machine.

@masonaxcte stylus to css not html
u can take look at my app.coffee, it compile stylus on the fly.

[masonwan]

@yyfearth I used the wrong word. I failed to compile client.styl to client.css. Could you test it for me?

@masonwan You need to pass a string instead of a buffer to stylus().

Oops, commented on a really old PR

@viruschidai thanks anyway, I often to make this mistake that use fs.read without an encoding.
