Deprecated dependencies

[rmg]

Currently npm install spits out some deprecation warnings related to some nested dependencies. It looks like upgrading to yeoman-generator@0.20.x will clear them up.

npm WARN deprecated CSSselect@0.4.1: the module is now available as 'css-select'
npm WARN deprecated CSSwhat@0.4.7: the module is now available as 'css-what'

Originally reported in strongloop/strongloop#243

Looks like #110 will resolve this if/when it is merged.

@rmg I'm closing this issue since #110 has already been merged... Thanks!
