v0.8.0

I just created a new stable branch and published 0.8.0 to NPM.

List is not very long but there are some nice features:

• sourcemap support (special thanks to Geoffry Song)
• fast mode (see https://github.com/Sage/streamlinejs/wiki/Fast-mode)
• [_] syntax to handle callbacks with multiple results (see README).
• cacheDir option to configure location of cache directory
• warning on modules that contain top-level async calls (only active in verbose mode)

I moved a few modules to separate packages:

• streams wrappers -> streamline-streams
• doctool utility -> streamline-doctool

I also did a bit of cleanup and removed some obsolete features:

• the require('streamline/module')(module) hack to enable streamline in *.js files
• the *_.js syntax for streamline source files.
  In short, you have to switch to the *._js and *._coffee extensions if you were using older ways to activate streamline on *.js files.
