Init Feature

Simple feature requested which adds a very basic type of project structure generation to fhc. At the moment it simply pulls down the ZIP of http://github.com/feedhenry-training/Basic-App and extracts the contents of the ZIPs inner directory into the current working directory (provided it's fully empty... whitelisting certain files/directories such as .DS_Store or .git can come in future updates).

Docs have been generated, patch version number bumped, should be good to go as far as I know.

It's also worth noting that I'm working on (much) more feature-full [grunt-init](http://gruntjs.com/project-scaffolding) templates for standard and decoupled projects, but these will be more useful internally in PS for the meantime and couldn't be simply integrated into fhc.
