Howl 1.0

[SquidDev]

Wrote down some ideas for Howl 1.0. Heavily inspired by Rake and Groovy, though I'd like to chuck some Gulp into there too.

The aim would be to make it more:

• Extensible: add the ability to write plugins
• Sensible: Incremental builds
• Powerful: Adding in support for source transformations, documentation generation, etc...
